  1. I understand you also sell the equivalent of LMR 400? Could you tell me, Brand, cost per foot and cost for SMA Female? Do you you also solder connectors to the wires?

    1. I do have some LMR-400, but I’m not set up to ship it; I sell it only for people who are local and can pick it up. The only connectors I have for it are UHF/PL-259, but it’s $0.75 / ft and is actually RFC-400, so not name brand but a respectable clone. I don’t stock it regularly; it’s something I’m considering doing, but the costs to get started are somewhat prohibitive at this point.

  2. Any Christmas specials this season on your antenna?

    1. Probably not, I’m afraid; I don’t have the inventory at the moment to do it justice. I don’t actually do specials very often — I’ve only ever done one online special so far. They are very time consuming to make and ship and I just don’t have the time to handle a large quantity of orders and build new antennas over the next couple of weeks.

      These are the challenges with selling handmade materials :-/ I can’t just order more in from China…

  3. Would one of these antennas work on a radio shack pro 91 scanner?

    1. I don’t see any reason that it wouldn’t, assuming you get the correct connector (BNC I think). I don’t know how well the antenna will perform on all of the frequencies, but should work well at least on the 2m/70cm freqs

  4. I want to use my UV-5R for hunting purposes (studying for my license as I write this). I don’t what a huge clumsy antenna, such as a Nagoya-771. I thought: Maybe go for a telescopic antenna instead, but from what I’ve read, the performance isn’t great.

    I saw your own review, but I had more questions:
    – Could you keep this antenna coiled up for the better part of a day, for a whole week or two of hunting without damaging it?
    – Could you receive a signal (probably not the best reception I agree but at least notice someone is trying to contact you) when the antenna is coiled?
    – Any problems shipping to Canada via USPS ground?



    1. In order:

      * You can coil it indefinitely without damaging it; it may not look as good if you do. It’ll start to hold a little bit of the curve is all, but never enough that it won’t work just fine. (and if it does send it back and I’ll replace it, because it shouldn’t)

      * I’m sure you could receive a signal when it’s coiled; I’m equally sure that your antenna performance would be *significantly* degraded. How much is more than I can say.

      * I have shipped to Canada before without any difficulty.

      1. Hi, this seems to be the only way to reach you. I ordered a Female whip and you shipped a Male. How do we fix this?…
        Thanks, David

        1. Hi David,

          The easiest way to reach us is always to respond to the order confirmation emails; if you can’t find that, just email sales@signalstuff.com and we’ll be happy to help.


    2. Just to give an idea of what you can expect wrt keeping it coiled up. I have a UV-3R in my get-home bag with one of these antennas, and it’s coiled up into a ~2″ diameter circle. This has been sitting in the bag like that for 2 YEARS. I just took it out and unrolled it, and it’s still straight at the base, with a very gentle (about 5 degrees by the tip, by the looks of it) curve in the upper half of the antenna.

      1. Just to be clear, I strongly discourage anyone from coiling the antennas that tightly — particularly the generation 2 antennas. I find that they are more likely to hold a persistent curve the more tightly you coil them when storing.

        My strong suggestion is that you coil it as loosely as you can while still fitting where it needs to go if it’s going to be left coiled for a long period of time! Strong variations in heat also make it more likely to pick up a persistent curve over time.

        That said, I’m glad you’re still happy with yours =]


  5. I cannot get your site to accept an order. On both iPhone and PC, using various browsers, it will not accept the First or Last Name, Address, Town, State, nor Zip.

    Please let me know if you get her working

    1. Thanks for letting me know; I’ll look into it right away!

    2. Everett,

      Could you please email us at sales@signalstuff.com with the address you’re trying to put in so we can try to reproduce the issue? I just tried with my own information and everything seemed to be working correctly, so we’re missing something.


  6. Hello, just got your signal stick for my HT- love it. I am wondering if you could make a version for a 25 W Mobile go box unit. Right now we are using telescopic antennas with a flex coil on the bottom to keep from breaking them. To run VHF and lower VSWR the radio go box (mounted on a backpack) has to be fully extended and if in wooded areas the operator needs to stop or risk the possibility of breaking the telescopic.

    What I am looking for is the longest possible dual band flex antenna that would work 2m/70cm in the Ham bands at 20w L and 25W H. I would like the longest that is electrically feasible.

    Long length is no problem and we envision something flexible like the PRC 77/25 whip antennas (except it would be your design style)


    1. There are two problems: First, without a matching coil (which I don’t currently have the ability to manufacture) a longer antenna would not actually work any better. Antenna lengths need to be pretty specifically calculated.

      The second problem is that nitinol is expensive to purchase and I buy it in bulk at a very specific size — the largest size I can get center pins for SMA connectors to crimp to, specifically. This size is only barely rigid enough to work well at the 18.25″ lengths we use for the signal sticks and if you make it much longer it will likely not hold itself up even under its own weight, much less if there is any kind of wind.

      So in essence, I’d love to help… but I don’t see a way that I could. Sorry :-/

  7. Yes this was the same problem we had trying to create a decent tape measure style flex antenna
    I might just try the one I got and see how it goes we do not talk on them long periods just short quick transmissions but will monitor to see if heat or vswr is an issue These are much better than using telescopic a that could be broken. For long periods of xmt we would use roll ups or fixed antennas just wanted something good if moving

  8. Hi,
    I wanted to ask if these antenna’s have any gain or if they are any better than the antenna’s that come with the HT’s?

    1. This is a more complicated question than you might think; the short answer is “yes, it should work much better than the antennas that come with your HT”. The long answer is here: https://signalstuff.com/2016/07/what-kind-of-gain-do-the-signal-sticks-have/

  9. Have spent an hour on your site and Facebook page. Cannot find a reference to match the descriptions of your antennas with your photos. The one in the center is what goes on my Anytone 3318 handheld. In July and August we will be using your Hamstudy with our youth club KC2RHY. Please visit our FB page. Thanks. 73 Jim N2OPS.

    1. I’m not sure I follow exactly what your problem is; if you go to https://signalstuff.com/product/super-elastic-signal-stick/ and choose a connector type and color (just choose black for description purposes) and the page should have whatever photos and descriptions you want. If you have specific questions feel free to email us at sales@signalstuff.com and we’ll do our best to help out!

      We’re very glad you find HamStudy.org helpful — we’ve worked hard on it and are hard at work on the next version! Good luck with your youth club!

  10. I have a UV-5RA and the antenna works really well with it. The rubber duck won’t pull a signal in a brick and metal office building (we can only get one FM station on a stereo). The signal stick does a great job and I am able to listen to the local morning net. And it fits just right and does not unscrew when you’re moving around (like my other more expensive antenna).

  11. How many watts of tx power can this antenna handle? I’m making my mobile go-bag and I’m thinking that since your antenna is so pack-able, what if I pack it along with my 50-watt mobile, would I need to keep my power down below a particular level? Love your antennas by the way! They are used regularly!

    1. You won’t damage the antenna. Keep in mind that the SWR of a handheld antenna is *far* less stable than what you usually use with a mobile rig, so it will probably end up reducing its power automatically because it will inevitably have suboptimal SWR — this is the case with any handheld antenna except possibly some heavily loaded ducks or larger telescoping antennas. It’s not going to give you optimal performance, but you aren’t going to damage the antenna.

  12. Any chance of seeing a dedicated 70cm version? It seems like it would actually be short enough for comfortable belt or shoulder carry, while still retaining the benefits of being ultralight and nearly indestructible.

    1. It’s something I’ve considered, but it costs basically the same amount to do a 70cm version as to do a 2m/70cm version, so we haven’t done much beyond making a few prototypes to test with. I’ll think on it again, since you bring it up; I have better tools to test with these days than when I last played with it.

      You could actually cut one down to 70cm if you wanted to — there is no loading, so all you’d have to do is cut it down the right length. That length would probably be around 5.5 inches, if my calculations are correct.

      Please note that doing so would void the otherwise lifetime warranty =]

      1. Personally, I would gladly pay the same price for a couple of those. For a product like this, it’s perfectly reasonable and expected to see the time/labor cost dominate over the materials. And I’m happy to pay for something that “just works”.

        I considered a DIY solution as you’ve suggested. Not too worried about the warranty actually – I already have a bunch of your antennas, and after experimenting with them in person, I’m plenty confident that there’s practically nothing accidental I could do to them with any reasonable likelihood that would break them.

        It just feels like a waste, though, especially since elsewhere you mentioned that Nitinol is not that easy to obtain – and the extra length that I’d have to trim could otherwise be two more such antennas. I’d rather you keep the extra material, and make more good stuff out of it :)

        1. This is definitely something I’ll consider; over the years as demand for these has increased I’ve had to find a variety of ways to improve my process. One of the things I’ve done is to find a company that sells me the nitinol pre-cut to the correct length. (Yes, I did a *lot* of testing before setting that length :-P)

          One interesting thing I found out as I sat down and did the math tonight, though, is that if you wanted to you could cut just over 6 inches (probably 6 and 1/16 inches) off the end and it should be the perfect length for your 1.25 meter (220) band. Even more interesting is that if you then take that remaining 6 inches and put a connector on it, maybe shave off 1/8 inch, you should have your 440 antenna.

          I haven’t done this and tested it on the analyzer yet (it’s far less simple than it sounds) but those numbers should work. Next time I build antennas maybe I’ll run off a couple dozen of each (1.25m and 70cm) and see if anyone is interested in buying them. I don’t expect BNC would be needed, since all the HTs I know of that are 440 only or that have 220 are SMA or SMA-F.

          Anyone else think they’d be interested in something like that? Chime in!

          1. I’ll ask around and see if anyone else might be interested hereabouts.

            One other thing that came to mind… given how light these antennas are, it’s not far-fetched to have a complete 2m/220/440 set, perfect lengths for each – I think it’ll still weigh less than Smiley’s collapsible tri-band, for example. The trick is coming up with a way to carry the ones that aren’t attached to the radio conveniently. Maybe you could join forces with e.g. guys at CountyComm, and come up with some sort of compact carry pouch – they seem to have some experience there – and then sell those things as a combo through them.

            Or maybe not even a pouch, but make the 3D printed base that covers the connector have some kind of hook-like appendage to dangle the other antennas from (after weaving them up into a loop)? Although that might affect the signal?..

          2. So far indications are that something like that would be relatively uncommon, but who knows what we might decide to do in the future? We’ll see what kind of demand there is.

          3. I just happened upon your page. Wondering if anything ever came out of this discussion. I too would pay the same price for dedicated 1.25 and 70cm antennas. I’ll be ordering one of your dual band antennas shortly. Can’t wait! Also would be interested in a length optimized for 6m.

          4. I’m still considering the 1.25m antennas; they’d be easy enough to do. I’ve experimented with the 70cm and I don’t feel they actually have any real advantage over the rubber duck, so I’m not strongly inclined towards them. Basically I just haven’t had time to play with it yet =]

            6m with the current design will not be happening, I’m afraid; the wire I have (which is the widest I can get connectors for so far) isn’t thick enough to support its own weight at the length the wire would need to be for that wavelength. If we ever develop a good way to develop a coil which is reliable enough for our needs then that might change, but for now…. sorry :-/

          5. I just ordered a dual bamd and have a BridgeCom 220mhz handheld. I would be very interested in a 1.25 version.

          6. I do actually have a limited number of monoband 1.25 meter antennas; they are the same price and I have them in both SMA-M and SMA-F. To order just order the connector you want and put in the notes that you want for 220; email sales@signalstuff.com to verify availability.

            Eventually I’ll find time to list them, but I’ve been working on a new version of HamStudy recently and it’s taken all of my time. =]

          7. I’d be interested in a GMRS variant (~465 MHz) as well as a 70 cm one – both/either with SMA-F connector/s. You might be able to make one length that will work well on both bands.

          8. Hi Leverett,

            I’ve actually made a few 70cm only variants; they are a lot harder to nail down than the dual band ones and end up being about the same length as a rubber duck anyway, so I haven’t found them to really be worthwhile to produce at scale, particularly since they cost basically the same as the longer ones; most of the materials end up being either the same or “close enough” and they actually take longer to make (because I have materials pre-cut for the normal length)

            That said, I’ve found that the dual band versions work adequately at GMRS frequencies; they may not be totally ideal, but they are pretty close.

          9. For me, the biggest advantage this thing has over a rubber duck is its flexibility – it means that I don’t have to worry about bumping it into something, or dropping the transceiver onto it, and breaking the connector. Also, you can coil it up for storage (e.g. in a backpack), unlike rubber duck.

  13. I have an Icom M73 marine vhf hand held with a female SMA (rubber ducky) antenna. Do you make antennas for 156.0 to 162.025 MHz?

    1. We don’t specifically do 156 to 162mhz, but you can tune it to 159Mhz (in the middle of that range) by snipping off 1.5 inches from one of our other antennas. As I have mentioned in other comments, doing so will unfortunately void the warranty (because I can’t then repair it for normal use if it breaks in a common way) but there is a reason that we offer a lifetime warranty — relatively few people ever need to use it, and nearly always because they dropped the radio in some way and it snapped the wire off at the connector. If you order one for this purpose, mention it in the comments and I’ll include a spare tip that you can superglue on after shortening it.

      1. Thank you for the quick (and favorable) response. I will certainly be ordering a few antennas and I look forward to using them. It sounds like the Nitinol antenna material used might be “picky” about the tool used to cut/shorten it. Is there a specific method/tool used for best results?

        1. It’s not actually picky about how you shorten it, it’s just that cutting it will notch most tools because it’s so hard. I use a heavy duty set of lineman’s pliers which seems to work out okay most of the time. I do have a leatherman tool that I need to get replaced because I notched the pliers pretty bad while cutting nitinol…. =]

          1. Got it, thank you.

      2. How much would I cut off if listening between the 152 and 156Mhz frequencies?

        1. … same answer. About 1 1/8″ (2.8cm)

  14. I am totally new to HAM radio. What is the suitable connector for my Yaesu FT-60R?
    I would like to order one. BTW, I am in Australia.

    1. the FT-60 requires an SMA-M connector on the antenna. See https://signalstuff.com/2016/08/choosing-the-correct-antenna-connector-for-your-radio/

      Also, just FYI “ham” is not an acronym and shouldn’t be capitalized =] (there is a wikipedia article about this with plenty of well documented sources)

  15. can you tell me the correct tune how much to cut? for gmrs frequencies i understand it voids warranty

    1. According to my calculations (and I haven’t tested this at all) to hit 462Mhz you’d need it to be ~5.75 inches long, which means you’d need to cut off about 12.5 inches. Keep in mind that the normal length working well on 70cm is a happy coincidence as it’s actually a 146mhz antenna, but if you’re just using it for GMRS there is no reason to keep it long.

      1. Should I cut from top down?

  16. I am buying a Yaesu VX-6R triple band – want to buy your flexible antenna- what connector does it use?

    1. See https://signalstuff.com/2016/08/choosing-the-correct-antenna-connector-for-your-radio/

      That said, the Yaesu FT-60, VX-{5-8}, ft-150, ft-170, and ft-270 as well as most other current Yeasu HTs all require an antenna with a SMA-M connector.

  17. I own anytone AT-3318UVE triband do you have anything for that?thanks

    1. We don’t currently have any triband antennas. You could use a dual band one on the two bands we do cover, but we don’t currently have a good way to manufacture triband antennas.

  18. How do I buy locally to avoid shipping? Thanks.

    1. You can contact us at sales@signalstuff.com to arrange a local pickup — I also nearly always have them at the exam sessions in Provo. That said, shipping is only $2, so it’s not that bad.

  19. I wonder about the length, 18,25″. Is that really a full quarter wave on 145 MHz?

    1. As a matter of fact, it isn’t =] A quarter wave on 145 Mhz would be 20.364 inches; however, radio waves actually travel at different speeds through different materials. When you calculate an antenna width you need to take into account not just actual wavelength but also Velocity Factor, which is responsible for most of the difference.

      The rest of the difference comes from the fact that a 1/4 antenna on a handheld is actually fudging things a bit — your radio and arm make up half of the dipole (and adding a tiger tail would just change the specifics, not remove the impact of that), so the best we can do is come up with a test harness that is “fairly realistic” and use that for fine tuning. I’ve done extensive tests over the last 15 years and I feel this is the best length… but I bet you could get very similar results if the wire was up to an inch longer or even shorter.

      It’s also worth noting that nearly all HT antennas are affected the same way — the ones that are less affected would be heavily loaded rubber ducks (which are practically just resistors anyway) or well designed telescoping ones which can provide a full dipole system in the antenna.

      Hope that helps!

  20. Does it work with the Wouxun KG-UV9D handheld radio?

    1. Yes it does; you need an antenna with an SMA-M connector for that radio.

  21. A Firefighter friend (N1DAE) had told me of your antennae, just ordered 2 SMA-F for my Baofeng UV82HP and an SMA-M for my Tytera MD-380 DMR.

    I’ve had my Tech ticket since 2001 and found out in 2016 that the CW requirement was dropped in 2004 – Boy am I slow :-) .

    Anyways I studied for my General and Extra through HamStudy and my other half (K1DAE) — [yeah the firefighter and my other half have the same initials — mind blowing at club meetings] had studied for her Tech, General, and Extra through the site.

    I am getting mine first to try them and she will order (through me) later. We are both VEs now and tell others of your site.

    We are proud to support such a worthwhile site. I also run our club’s website (n1me.org) and are going to put in a link to your site for people to study for tests.

    Keep up the great job.

  22. I Have a Yaesu VX-170 and have a couple of questions.
    1) I need a SMA female antenna (the radio has the male portion) but when I click on it I get a pic of a male antenna I need to make sure I get the correct one.
    2) The VX-170 is a waterproof unit as well as its rubber duck antenna/connector. I use this radio in the rain and in blizzards and need to maintain the waterproofness. Will your antennas provide a waterproof seal?

    1. It’s good that you asked — your radio actually has a SMA female connection on the radio, thus you need an SMA male antenna. The gender is determined by the center conductor, not the threads. Thus since your radio has a socket, it’s a female connector. The antenna has a pin, so it’s male.

      1. Thanks for the clarification on the thread vs conductor being the determining factor on the male vs female. Does your antenna keep the waterproofness of the radio?

        1. Ack, sorry for not responding completely. No, our antennas will not make a watertight seal. Most aftermarket antennas won’t in fact.

  23. So I have read threw the comments and didn’t see this question, if it was already asked I apologize. Will this antenna make the radio top heavy? I have a Baofeng with an aftermarket nagoya antenna and it makes this little thing so top heavy it barely stands up in its own. I am thinking of putting one on my Yaesu FT2DR which is a slightly bigger radio but I was just curious. Thanks and 73 de W4JRQ

    1. I think most would say that no, they don’t make your radio top-heavy. These antennas are extremely lightweight, but they are also ~18.5″ long, so while compared to most antennas (even some rubber ducks!) they will not make the radio top-heavy, if you set it upright and the antenna is swinging it will still probably knock it over =]

    2. @Jesse: I have a Yaesu FT1xDR with one of these antennas on it, and I have no issues with the antenna knocking over the radio, even if the antenna is swaying when I set the radio down.

  24. Hi,

    I bought one then another of these Signal Sticks and am satisfied with them. My question is I have a 10m HT and there seems to be virtually no HT antenna that is adequate enough short of a 1/4 wave. I have purchased some Nitinol wire and am attempting to duplicate the 2m version. I know it will be inordinately large at 10m, as a quarter-wave is going to require a minimum of 8.5 feet, but Nitinol is easy on a BNC chassis mount whereas a 102 inch steel whip definitely is not. Are there any sellers out there who provide the shrink tubing with parallel memory properties to cover the Nitinol wire. And PS I figured out how to solder the Nitinol into the BNC. Stretched out the wire is highly efficient, even at the bottom end of the cycle.

    1. Hi Richard,

      You’re absolutely right about the length being excessively long =] More concerning than the convenience of such a thing, though, I’d be concerned about the relatively high resistivity of nitinol wire; at the length that a HT antenna is the resistivity is acceptable, but when you make it that long I’d be concerned that it may be too high for the antenna to perform. The SWR may look fine, but that could be “fine” in the same way that a 50 ohm resistor has very low SWR =] Just something to watch out for.

      That said, you can buy spools of heat shrink at various places; you’ll need to match it to the diameter of your wire, which can be tricky, but you shouldn’t need anything special to match the memory properties of the wire as most heat shrink is flexible enough that it can be bent or coiled just fine.

      73 and good luck with your project,


  25. Got the antenna yesterday and I love it. Couldn’t believe it was in that little package. Thanks

  26. I am an italian Ham and in my country ham band are 144-146 and 430-440 mhz. A bit different from USA. How perform your antennas within this range?

    1. They should work just fine on those ranges; 70cm may not be 100% ideal, but should be good enough.

  27. what is the frequency coverage with this antenna? Also how well do you think that it would work with a Yaesu FT2DR because I am looking for an antenna that can be used with all the frequency ranges that this radio can handle.

    1. These will work well on 2 meters and 70cm, but not particularly well on 1.25m (220).

      1. So how well will it work with Am frequencies and UHF frequencies

        1. I’m not actually sure what you mean; when you say AM, are you talking about AM radio, as in 535-1605 kHz? AM itself is of course a modulation type… assuming you are talking about the AM broadcast band in the US, I would expect it will probably work as well as most short antennas, which is to say not particularly well but better than nothing as long as you’re just receiving (that’s about 200 meters, lower frequency than even the 160 meter band). You could also be talking about the AM aircraft band, though, which is in the 120Mhz range somewhere, and they will work decent for receive but not great for transmit there.

          When you say UHF frequencies, what do you mean? UHF is commonly used as a shorthand in ham radio for the 70cm band, but I already told you they work there, so are you talking about something else? UHF actually refers to all frequencies between 300 Mhz and 3000 Mhz; it will work on some frequencies in that range, but certainly not all. These are dual band antennas which are specifically designed to work in the US amateur 2 meter (144-148Mhz) and 70cm (420-450Mhz) bands, but will work on receive in other bands.

          I hope that helps; if not, you’ll need to be a little more specific.

  28. Do to a shipping error or possibly someone stealing the shipment during the Holidays I did not receive my antenna. But Thanks to Signal Stuff I received an antenna today. Richard sent me a antenna and i am gratefully for their commitment to their customers.

    Thanks again Richard.

    1. Glad to help, Steve. 73!

  29. […] (if anything) or transmit far. If you are limited to a whip antenna only, I highly suggest using a SignalStuff Antenna, made and sold by the gentleman who has brought the amateur radio world HamStudy.org, otherwise […]

  30. Looking for a better antenna for my handheld Yaesu FT-250.
    I would also like to be able to connect it to a magnetic roof top antenna.
    Do have the parts I need, or can you direct me to a source?

    1. Hi Marty,

      We can definitely fit your FT-250, but we don’t have any resources for magmount antennas. The materials we have aren’t suitable for a rooftop antenna.

      Sorry I can’t help more!

  31. Your compatibility list shows: Baofeng UV-3R (not UV-3R plus and very few others!). I have a UV-5R and want to ensure this will work on my radio before I order. Thanks.

    1. Well spotted! For the UV-5R you need the SMA-Female connector, not SMA-Male =]

      It’s on the list for the SMA-Female connector.

  32. I’m trying to order but shopping cart doesn’t like my address.

    1. Email us at sales@signalstuff.com with details on what you’re trying to do and we’ll see if we can help you out!

  33. Brilliant Antenna! I purchased two with different connectors. Both arrived safely here in the UK today. They work a treat. Excellent quality and I will be placing another order.
    Keep up the good work.
    73 from across the Pond

  34. I have received the dual band 2m/70cm SignalStuff antenna and have been it putting thru the paces… Field Day 2018, travel back to Omaha from Virginia. This is a fantastic antenna that is easily out performing the SR320A that has been my go to antenna. An example of that would be testing both antennas on my Mirage BD35 amp I travel with and the SignalStuff antenna allows connection to a local Winlink node while the SR320A does not connect. I have tested this set up several times throughout my stay and the results are always the same. Another example is my ability to both receive better signal and transmit more reliably thru local FM repeaters using the SignalStuff than the SR320A on my Kenwood TH-D74. I was skeptical but am now a believer and am recommending this a less expensive upgrade to my local CERT and ARES/RACES teams.

    1. Thanks for the detailed review! Glad it’s working well for you — let us know if you have any problems!


  35. […] (if anything) or transmit far. If you are limited to a whip antenna only, I highly suggest using a SignalStuff Antenna, made and sold by the gentleman who has brought the amateur radio world HamStudy.org, otherwise […]

  36. Amazing antenna from an amazing group of Hams!

  37. what is the best way to contact you to pick up a couple of antennas or help you build them?

    1. It’s nearly always easier to just order them — shipping is only $3.65 (I had to raise it recently so that I could insure packages; USPS was losing too many).

      If you are local to UT county or close enough to help and would like to the best way is to join the facebook group https://www.facebook.com/groups/signalsticks — note that this is a closed group and I will only accept people who are local and able to help build antennas. It’s not a place where I discuss antenna theory or anything, just a place where I post announcements about when I’m going to be building antennas =]

      Hope that helps!

  38. Hello,

    I have seen many folks talk about your antennas, and decided to take a look on your site. The wire you are using looks really cool. As I started to place an order, I now have a couple of questions. Your antennas are to mount on a Yaesu VX-6R (so, SMA-Male is required)…

    / What exactly is the rubber spacer option you have listed? There is already something of a rubber ring/base for the antenna.

    / The glue cap looks pretty bulky… Any problems with it seating fully and not interfering with the screwed in plug to fill the Mic/SP jack?

    In closing, I am looking into pulling the AM/FM radio setup out of my vehicle and swapping in an appropriate antenna mount w/ feed line. Would you cut a custom length antenna? (of course, non-returnable, etc.).



    1. Hi Mike,

      The rubber spacer is just a 1/4″ ID, 1/2″ OD, 1/16″ thick rubber washer which fills the gap which exists on some radios between the antenna and the radio. It only fits SMA connectors and it is rarely needed for SMA-F, though I’ve seen a few exceptions. Not all SMA connectors on radios stick out the same distance so we can’t make the antenna just “fit” on every radio the same. It’s purely an aesthetic thing — no radio actually *needs* it, it just looks a little nicer and may provide some additional stability / stress relief to the connector on the radio.

      Even with the glue cap, signal sticks tend to be slimmer than most other antennas — I’ve never seen an issue on any Yaesu radio, including the VX-5, 6, 7, or 8.

      Signal sticks aren’t ideal for car mount antennas — the wire is not rigid enough to stay vertical while driving. I will provide cutting instructions for specific frequencies to those who want them, but you’d need a longer antenna, not a shorter, and most of the supplies I get these days are pre-cut, so that’s not easily accomplished.

      Hope that helps!


  39. I have a question about the difference between generation 1 and 2. Been searching on the page and have not come across the difference. Thanks for any information.

    1. If you select all the options details about the particular combination will display — so select “dual band”, “2nd gen”, and one of the connector types and you’ll see the description. I’ll have to look for a more clear place to put it :-/

      1st generation is what we’ve been selling for years; 2nd generation we started selling early September, 2018 — the wire is 36% thicker and is much more rigid. Still can be coiled just fine but somewhat less prone to wobble around all the time — it’s also stronger and less prone to snap off, which is the most common reason antennas are returned under warranty (which can still be done with 1st gen antennas — as long as we’re alive the warranty holds).

      That said, the old antennas still work fine just like they have all these years; we have a few left, so we’re selling them at a discount until they are gone.

  40. If you ever make an NMO mount version please let me know. I would love to buy one of these for the top of my Jeep. Bushes and canoes are often on top of my roof and having a quality antenna with lots of give would be perfect.

    1. Wish I could :-/ I keep looking for a coil I could use as a base, haven’t found one yet.

  41. Just wanted to say thanks; your antenna is the best I have ever used.

  42. Do you have a supplier in the UK where I can purchase these



    1. Unfortunately no. Our margins and volume aren’t high enough to make resellers / suppliers make sense; we manufacture them all ourselves with help from local hams (in my garage, usually) and it’s sometimes a struggle to keep them in stock as it is.

      Until early this year we were able to ship them internationally for a reasonable price (about $2.50USD) but unfortunately that shipping method was discontinued and we had to raise shipping prices. Your best bet would probably be to do a group order since shipping combines pretty well — i.e. it’s not much more expensive to ship 10 antennas than to ship 1.

      Really sorry, I’ve spent hours searching for better options but had to settle on this. There is a shipping method that is $4.79USD that I could re-enable, but as it has no tracking available I can’t put any kind of guarantee that the antenna will actually arrive. After a few incidents I gave up on it.

  43. Any plans do do a mobile version?

    1. Unfortunately not at this time; there are a number of technical challenges and frankly we’d rather spend the development time working on HamStudy.org =]

  44. I am sorry if this has already been asked but I was wandering what the frequency range is for the dual band super elastic antenna you make? Thank you in advance.

    1. They are designed to work on the US amateur radio 2 meter and 70cm bands (144-148MHz and 430-450MHz) with the strongest signal at 146MHz and 446MHz


  45. The antennas I’ve seen, though it’s hard to tell from the pictures, seem to be a single, flexible rod. No traps are visible. Since the 2m and 70cm bands aren’t even multiples of each other, is the dual-band antenna resonant on one band and poorly matched on the other, and if so, which ones?

    1. I can well understand your confusion =] You are correct that there are no traps, but not entirely accurate as to the mathematical relationship. 146 * 3 = 438, which is close enough to be a very near match on the 440 band using it as a 3/4 wave antenna. So, it works out that it’s a 1/4 wave antenna on 2 meters and a 3/4 wave antenna on 70cm. It will absolutely give the most benefit on 2m but still does respectably well on 70cm.

      You can find an SWR graph taken using a real live signal stick here: https://signalstuff.com/wp-content/uploads/2016/05/g.png — note that getting reliable SWR readings out of an antenna like this requires you to isolate the antenna from the analyzer system, so don’t expect to see identical readings just by plugging it into an analyzer (the analyzer is itself changing the SWR). To get reliable readings you’ll need to use a choke balun (or large ferrite) and some sort of counterpoise.

      Hope that helps!

  46. hi i need this antenna but with pl 259 to see if you can do it and how much the cost please thank you very much for your attention

    1. Hi Wilfredo,

      Unfortunately it’s not viable for us to do custom connectors. You could get a PL259 to BNC adapter and then purchase one of our BNC antennas, though!


  47. https://signalstuff.com/product/super-elastic-signal-stick/ shows 8″ as a dimension under additional information, but under features, they’re either Approximately 18.25″ or Approximately 12″ long depending on bands…

    1. Huh; yeah, that’s the shipping dimensions, which I have that way so that shipping labels generate correctly (they ship coiled). I’ll have to see if I can hide the “additional information” tab or else make it useful somehow.

  48. […] came across the Signal Stuff, Super-elastic Signal Stick in a recent on-line article. As you can see in the image, it is tied in a knot. And that is exactly […]

  49. Quick question regarding warranty: Does the warranty cover storage in a knot, like how it was shipped? I want to keep it compactly stored in my bag but I don’t want to void my warranty in the off chance that it becomes damaged somehow (though I don’t expect that of Nitinol).

    1. The warranty covers anything except intentional damage — so basically as long as you don’t intentionally cut the wire we’ll cover any damage.

      If storing it I would recommend not coiling it any more tightly than you need to as if stored for long enough it could be exposed to high enough temperatures that it could start to retain some memory, but yes, if it gets too bad and you need to get it replaced we will honor the warranty. The advice is more to avoid you the hassle =]

      Hope that helps!

      – Richard

  50. Hello, I just received the signal stick for a Baofeng UV5R+ HT. So far it seems to work very good, Thanks!, And I did use HamStudy.org Years ago, And it did help me a lot, So it is nice to give a little something back to help others. KB3DWQ

  51. Can you give me the weight of your 2m/70cm antenna with a SMA male connector? Thanks! Greg

    1. It’s a little under 0.5 oz

  52. I ordered an antenna with the BNC connector on June 3 (bank account confirms) and have not received the order, nor have I heard when it is going to be shipped. I would appreciate contact from someone so we can discuss my order. Thank you. 503-522-7991

    1. Hi Scott,

      I emailed you when you placed the order and I responded to your query — you are apparently not receiving my emails, so I’m not sure what else to do =] Hopefully you’ll see this.

      Due to some recent issues with our supplier (a large bad batch) we’ve been out of stock on BNC antennas. The good news is we *should* be receiving the new materials any day, assuming we can get them through customs (never had this problem before but they’re 2 days delayed now).

      Please check your spam filter or contact us on facebook or something… happy to give you more details, but my previous attempts seem to have failed =]



  53. Newbie here, trying to learn and make decisions :)

    Regarding the 2m/70cm elastic signal stick ..
    “Dual band – 1/4 wave on 2m (144-148Mhz) and 3/4 wave on 70cm (440-448Mhz)”
    I see different manufacturers adverts slightly frequency ranges.

    The antenna is specifically tuned to perform best at these frequency ranges on each respective band? How does it perform outside of these frequencies?

    I am in Australia, our allowed amateur frequencies are
    2 metres 144.000 MHz – 148.000 MHz
    70 Centimetres 420.000 MHz – 450.000 MHz (Or 430.000 MHz – 450.000 MHz on standard license)

    However UHF CB frequency is 476.425 – 477.4125 MHz

    And I also have a client using 164.25 MHz

    Would a signal stick still perform well outside of the advertised frequencies or should I me looking at other antennas?

    Many thanks from down under!

    1. The further away from those frequencies the less well it will work; your 2m/70cm frequencies it should be fine, and it will function on the others but I don’t have enough data to say exactly how well. You could trim it down a bit to make it work better on the higher frequencies, but that would of course void the warranty.

      1. Great thanks for the reply!!

  54. Hello, Do you sell the nitinol whips seperate? I am working on a mobile hf antenna project and would like to find a section of this whip material about 120″ long. Can you sell this to me?

    1. Hi,

      Unfortunately we purchase our nitinol pre-cut to the lengths we need these days. I’d check ebay or aliexpress and see if you can find the lengths you need there.


  55. Hi, would Super-elastic Signal Sticks be and upgrade to some Retevis H-777 radios I have been using?

    1. The H-777 is UHF-only; while the signal stick should work decently well with it it’s unlikely to be a significant upgrade because the antenna which comes with it is already pretty much a 1/4 wave length (resonant length). Since the signal stick is a 3/4 wave on UHF it acts more or less like a 1/4 wave and unless the stock antenna is designed very poorly the stock antenna on your HT should be reasonably close to the same.

      That said, you’d have to try it to be sure.

      1. great thanks for the information ! I just might try it, and if not can always use on my BaoFeng

  56. I’m just getting started with this type of communication equipment. Don’t hate, but I’m starting real simply for close family and neighbors, for now. I’m looking into the RETEVIS RT27V MURS VHF 2 watt radio. Do you have something that will work with these 2 watt VHF radios? Appears to be the standard “rubber ducky” connector.

  57. I saw a number of mentions of these Super-elastic Signal Sticks from Signal Stuff. Everyone who had one seemed very pleased. Often reviews are biased or paid for in some way but they seemed genuine so I risked ordering a couple as I have numerous hand portables and scanners using everything from the standard cheap “rubber duck” that many come with to various Nagoya and Watson aerials that were rated by various users. All the aerials I have used have been dual 2m/70cm models which I also use for some airband and nautical channels.

    I have been amazed by the Signal Stuff aerials. Their performance is excellent and the flexibility of the aerial is beyond belief. I would recommend these aerials to anyone who is serious about their comms. Highly recommended and a very fast turnaround from ordering here in the UK to the aerials being shipped (same day) and arriving four working days later here in the UK, Excellent all round and well worth the money.

  58. Hello,

    I just bought the brand new Yaesu FT3D.

    This radio has got a gigantic GPS hump Top dead center. Could you check to see if your antenna with the SMA-M connector (I think), will fit here?

    Thank you,


    1. Hi Bob,

      I can’t say for sure — I don’t have a FT3D to test against — but the max diameter of the SMA-M connector that fits that radio on the current signal sticks is 12mm, so as long as there is at least 6mm from the center socket on the connector of the radio to the edge of the GPS hump you should be fine.


  59. I want to make sure I buy the right antenna. I have a Baofung UV 5R. Which antenna do I order?

    1. SMA-F antenna for a UV-5R

  60. Hello Richard. Is there a Black Friday Week this year? I think so the last few years. Need one for my Yaesu FT 3rd generation so it bends slightly less in the cold winter. Greetings vy 73, Jürgen DK4BU

    1. I’m just setting one up for 2019 this year =] Watch for an announcement.

  61. Does this antenna work on the 10m bands as well? I see it works on the 2m and 70cm bands

    1. No, for a 10m antenna you’d need something *much* longer or with a serious loading coil which we don’t have the capability of building at this time.

  62. Hello from the “Big Easy!” I just ordered one of these in SMA female for my Yaesu FT-4XR and an Ailunce HD1 DMR HT. I can’t wait to try it out against a Diamond SRJ 77CA. So far, the Diamond is the best performing antenna I have right now for my HT’s. I have a feeling the Super Elastic Signal Stik is going to out do the Diamond! 73 from KJ5GUY!

    1. I’ll be curious to hear how it performs =] That diamond is a well designed antenna — it’s definitely one of the best on the market regardless. 73!

      1. Well Richard I can honestly say that your product will compete well with the Diamonds! I was able to hit repeaters from inside the radio room at work(I am a comm officer for local LE)where I normally can not. Both antennas were able to actually “kerchunk” the repeaters and I was able to hold QSO’s practically full quiet on them except for a 2meter but I was still fully readable but with some hash. That particular repeater is at least 20 miles away! The Signal Stik will definitely compete and give the Diamond a run for its money. Speaking of money I believe your price point is much better that the Diamond which sells for as much as 35 bucks! Thanks for making a great product!

  63. I just got a Yaesu FT3D, my first radio. HRO said that a different antenna would provide better signal, so I purchased a Diamond SRH77CA

    Frankly I’m receiving fine, but even repeaters 5 miles away do not acknowledge my transmissions.

    Are the specs on your antenna so much better than I would see an improvement?

    1. Hey Joe,

      Well, I’d like to think we make a pretty darn good antenna — but it isn’t magic, and though I’d of course never admit as much in public Diamond also makes a very respectable antenna. I’d guess that much more likely is that there is enough between you and the repeater that it isn’t going to make much difference which antenna you use. I suspect if you stand on your roof with a rubber duck you’ll get in just fine, but positioning in a case like yours is more likely to help than another antenna. In short, I would not expect the signal stick would show an improvement unless your Diamond antenna is not performing correctly.


  64. Quick question Richard, how many watts will the Signal Stik handle?

    1. I don’t know exactly, but well in excess of 50 watts.

  65. I recently purchased 2 of your signal sticks for UV-5R’s. Great and durable product with equal or better reception that other antennas I have.

    I recently ordered a UV-5X3 Tri-band with 1.25 M. Any idea how a Signal Stick with that 222-225 MHz band?

    1. The dual band version will not work super well on 1.25m, but we do have a monoband 220 version which will work great on that band.

      1. is there a cable and connector needed to connect this to a UV-5R, I have been looking at getting one of these as well, i would like to see a picture how it all attaches.

        1. By “this” what are you referring to? For the Signal Stick no; for the Signal Staff (OSJ) yes, you’ll need a coax. I’d recommend getting something RG-8X with PL-259 on one end and BNC on the other and getting a SMA-F to BNC adapter to put on the radio to connect to it.

  66. Help, just got the J-pole. On the panel labeled “1”, 1 additional rod is threaded with an OPEN top, correct, per your directions.
    With the panel labeled “5”, I add 4 sections with the last section being either one of the two rods with the closed top (depending on whether you want to hang it), correct?
    This gives me one rod (in the 5 section) that is NOT used?
    Your photos are confusing to me. Help.
    Dave, K6WDE

    Nope – looking at the internet, the tall piece has to be 57.5″ by design and the shorter one is 19.25″. All rods are then used, contrary to your pictures and directions. The closed top rod with the hole can be moved to the taller section if you wish to hang it. Wow.

    1. Hi,

      Not certain where the pictures are losing you; I’ll try to write up something more detailed soon.

      One rod on each hole in the base, shortest by 5 and longest by 1. Middle is closed top.

      By 1 you add 1 section (closed top). By 5 you add 5 sections with the top most closed. All parts are used.

      It you are still having trouble email support@signalstuff.com with a phone number and I will have someone call to clarify.

      Sorry for any inconvenience!

  67. I may have left this question in the wrong place before.

    If I put a 220 MHz Signal Stick on an Alinco DJ-G29T, how resonant do you think it would be at 903 MHz (the other band this HT supports), where many repeater inputs live?

    1. Really any of the pages is fine for these questions. Honestly I do not know for sure, but I don’t have any reason to think that it would be particularly resonant at that frequency. It might still be good enough to be usable, but I really don’t know.

  68. I bought six of your signal sticks to pass out to friends. I like them. They work well, make a difference in T/R – at least on my little Baofeng. Two questions. (1)The stick I have spins in the base probably because of storing it on the radio coiled and twisting the coil to make it fit in storage. Does this damage the antenna? Does it degrade performance? And (2) will it fit an Anytone HT which is also SMA Female?

    1. Hi Lorenzo,

      Spinning won’t damage the antenna, but if it spins it is lose and can pull out which would make it not contact the radio and in that case it would not perform well (or at all) until you pushed it back in.. Send us a pic (sales@signastuff.com) and we’ll get that replaced for you.

      It should fit an anytone HT just fine as long as the anytime is expecting the same connector.
