(12 customer reviews)

Now offering quantity discounts! See below for discount table.

Please select the frequencies and color that you want below — the “classic” signal stick is “Dual Band” and “Black”.

PLEASE check the connector against the pictures before ordering — many people mix up connector types and genders!

NOTE: Some radios have an abnormally long SMA post on them which leaves a gap between the radio and the antenna. You can add on a spacer to fill that gap if your radio has that issue.

Connector: SMA Male

Please look at the images to make sure you have the correct connector! We usually have two or three orders per month that are sent back because the customer mixed up male vs female (the gender is determined by the center conductor, not by the threads!).

These are hand-made, ultra lightweight, and nearly indestructible antennas which outperform the stock antenna your handheld radio came with by a significant margin. Originally designed to use as a fundraiser for a youth group, sales from these remarkable antennas now provide funding for HamStudy, ExamTools, and other initiatives which help support the Amateur Radio community.

All Signal Sticks are hand made; if you are looking for perfection in aesthetics then these may not be for you, but our design is continually evolving in order to provide better looking, better functioning, and above all more durable antennas.

See Ham Radio School’s What’s that connector on my HT?. If the center conductor on the SMA connector on your radio is a socket, this is for you.


  • Frequency range:
    • Dual band version – 1/4 wave on 2 meter (144-148Mhz) and 3/4 wave on 70 centimeter (420-450Mhz)

        • This SWR chart was taken using a balun to isolate the antenna and a ~18″ tiger tail to stabilize the SWR. Take it with a grain of salt, but it’s fairly accurate as far as it goes.

    Excellent order in accuracy and speed. I was told it may be about 2 weeks for shipping, but I’ve received the antenna in about a week.

    The Signal Stick is pulling in RX that the other aftermarket antenna I was using couldn’t find. It’s well made and it’s a bit taller, thinner and lighter than I was expecting…that’s actually a good thing in my opinion. I chose the blue dual bander. The blue makes it stand out but not in an unpleasant manner.

    Overall EXCELLENT!

  2. Ben Cottman

    Excellent customer service and quality. Works extremely well with my FT60R. And yes, you can bend into a knot and it bounces right back to straight. With the available bushing to fill the gap, the antenna seats tightly and looks good too.

  3. David Donoho

    I love the signal stick. It is a high quality — no worries — antenna. I remember someone talking about how they accidentally closed their car door on their signal stick and it was fine. Yup! I have done that too.

    Just now my one year old got ahold of the antenna that was sticking out of a bag that I had packed. He was jerking on that antenna trying to break it free. It didn’t occur to me till after several minutes of watching him that I never would have let him do that to any other antenna.

    Due to its ease of use, but high quality, it is a preferred antenna when I go up into the mountains for service work.

    The best antenna I own and I have a few. I mainly use it to scan frequencies. Works great.

  5. James Cervantes (verified owner)

    This is my second antenna from Signalstuff. It’s the best. Looks good too.

  6. Curt

    Great antenna. Better than my (Real) Nagoya 771.

  7. KM5SE

    I finally replaced my telescoping antenna with a Signal Stick. The flexibility keeps it from hanging on objects and pulling at the connector jack…or breaking. What I did not think about is how light these are; it is probably lighter than the stock rubber duck! I am coming back to buy more for my other radios.

  8. Christian

    Works excellent on our HTs. This is the only antenna that I had so far that works really well on 2m. What I noticed is that when it gets cold, close to freezing, the material becomes easily deformed. When it gets warmer, it comes back to its original form.

  9. Shane (verified owner)

    Very happy with the quality and superior build of this antenna. The SS team did it again! SWR is perfect right out of the box!

  10. Kyle Mills

    Amazing antenna
    -Super durable
    -Super light weight
    -AWSOME gains over rubber ducky
    Cool color options!
    – Great price!!!!!
    -Made buy a small business that helps HAM’s!!!!!
    – Did i say durable?…..well its durable ok….
    – Not sure if i said it looks cool yet but it dose

    Can you tell im excited about this 1/4 wave? Im putting this on all my HT’s from now on. And, hay “signal Stuff” guys….. make an NMO mount 60” whip for our mobil rigs!!! I will buy one RIGHT meow.

  11. Kevin Horikawa (verified owner)

    I picked up a SS antenna for a FT-60 and it is amazing! Side by side next to a VX-5R with a Diamond SRH77CA, the RX signal is noticeably better and picking up repeaters is hands down better. I’ve even swapped antennas to make sure it wasn’t a difference with the HT.
    I just placed an order for another SS to replace this Diamond antenna.

  12. Scott (verified owner)

    Grabbed an orange one for my Wouxun KG-UV9D Mate. Orange color match is almost perfect, the antenna performs better-than-stock as expected. Super flexible and strong. The glow-in-the-dark tip is a nice touch so it can be seen in the dark, no surprise poking someone with it. Note, you will need a spacer or two with this unit and antenna!
