The Signal Staff is a dual band 2 meter / 70 cm Open-Stub J-pole from S&K Antenna Systems!

This is a new antenna for us here at Signal Stuff made by S&K Antenna Systems who are friends of ours and have assisted in many aspects of Signal Stick manufacturing! We will have more information as we go, but to get them up and listed we’re working incrementally.

The base to this is designed to mount with a 1/4″-20 threaded screw such as is commonly used to mount cameras; this makes it easy to use a portable tripod or any other mount used for cameras. If you want to mount to an antenna mast please also order the “Mast-mount bracket for the Signal Staff OSJ

  • Dual band (2m / 70cm)
  • Strong, rigid construction
  • Easily fits in your go kit!
  • SO-239 connector
  • Lifetime warranty against factory defects; damage due to misuse or accidents are on you.

You can find assembly instructions here. Read below for more information!

NOTE: You will need to provide your own coax to connect this to your radio. If you plan to use it with a handheld transceiver (HT) we recommend using a BNC adapter that fits your radio and then get a PL-259 to BNC coax to make the connection.

Description

The dual band Signal Staff might just be the best antenna for a portable go kit; though fully assembled this antenna is about 60 inches tall, it collapses to fit easily in a small bag with the longest piece only 11.5″ long! Pair with a simple foldable camera tripod and you have an antenna you can carry around with you wherever you want to go which can handle as much power as you want to push into it!

full sweep SWR

  • SWR as low as 1.06:1 on 146MHz
  • SWR as low as 1.37:1 on 440Mhz
  • This antenna can easily handle 500 watts — we haven’t pushed the limit to see what the max power capacity is, but suffice it to say you aren’t likely to hit it.
  • Collapses to a super portable 6″ x 12″ x 3″ (maybe smaller), weighs only 2 lbs (900 grams).
  • SO-239 connector (UHF female)
  • Designed by real hams, made in the USA

    A must have, and an incredible value. I live in the virgin islands and I have to say I am impressed with the portability, quality and robustness of this antenna. I am pleased with the signal quality and look forward to other possible bands. This is also a great scanner antenna and makes a great addition to my emergency preparation communication system. Thank you!(make sure to order the optional bracket)

    I love this antenna. It fits my situation in 2 ways. 1. Portability. I live in a condo and can set this antenna up in minutes and reach repeaters in town. 2. I can take it with me for SOTA and when in mining camp I can have a base operation setup. Thank you for this amazing, well constructed antenna. Im sure I will get years of use with it.

    Absolutely fantastic antenna. I live in a HOA restricted neighborhood and I mounted it in my attic. The fact that you can hang it is invaluable. I am about to get a 2nd one for mobile operations.

    Excellent antenna. I used it for a SOTA activation on a 13,000 peak in the Sangre de Cristo Mountains. Paired with a Yaesu handheld. Made 7 contacts including one 86.7 mile contact to another climber on Mt. Bierstadt. I’ll be using it for an upcoming ham 14er/SOTA event in the Colorado mountains.

  5. Bobby D

    Used this antenna on a camera tripod during 2 meter SOTA activation today W6/NS-121 and made 31 contacts with all great signal reports! I highly recommend KN6IWN
    Note: it’s a bit heavier but super solid construction and handles up to 500 watts I believe.

    Great antenna, transmits and recieves well, easy to assemble and mount on a tripod.

    The only thing I can think would improve it is milling a little divot in the bottom of the threaded end, and adding a spot of coloured paint to make it easy to assemble correctly (I modded mine)

    Wonderful Antenna. This is my main VHF/UHF antenna. I have it mounted on my fence, and hooked up to my Icom IC-7100. I haven’t had a single issue with it. I can receive and hit every repeater within 40-50 miles easily.

    The antenna was extremely easy to setup and get mounted as well. I have recommended this antenna to quite a few fellow Hams.

    This is a great antenna. Mounted on a tripod and connected to my Yaesu HT, it is a solid performer for 2m and 70cm. I can also pull in shortwave broadcasts from Europe and Central America since the HT is broadband receive. I’m very impressed. Highly recommended!

  9. Andrew Roper (verified owner)

    So far, so good! This is my go-to antenna for 2m and 70cm in and around my area. Works great on both bands on my ic-705 and FT3D. Also very easy to assemble/disassemble and it fits nicely in my small go bag. I have no tripod yet, so I hang this antenna up in a tree if I am doing field work. Great antenna.

    I set this up in my basement attached to my handheld and it works great!!

  11. jordan.buckley (verified owner)

    Excellent build quality! I’m not sure you could make one this nice for the same price yourself. Worked perfectly with as advertised SWR out of the bag! Will likely buy another one.

    Excellent build quality! I’m not sure you could make one this nice for the same price yourself. Worked perfectly with as advertised SWR out of the bag! Will likely buy another one for stationary use.

  13. Jason Harris (KI6LXY) (verified owner)

    All I can say is, WOW! This antenna is really nice. Well made, durable construction, and performs really well. We were able to hit, and receive repeaters 55 miles away. If you want a great performing antenna, at a reasonable price, buy this antenna.
