    POTA has become my favorite way to ham radio this year. We usually end up with best results on 20m and 40m.

    A friend told me about this antenna. I ordered it and built it.

    It's an easy build, here are the instructions

    I had to trim the 20m section a bit to dip the SWR, as I did, 40m came into line also.

    Took it out today and activated K-0998 Horseshoe Lake, across from STL.

    It worked wonderfully. I quickly ended up with a pile-up and made 60 QSO's.

    I much prefer resonant antennas over using an antenna tuner.

    This antenna is perfect for portable use.

    Very happy with this antenna, especially given the low price, under $30 shipped.

    Nice!

    I just picked up two of their other antenna kits: the trigger-band vertical and the DS1 with the optional 40m loading coil kit.

    Looks interesting, thanks for the review. I went ahead and ordered one to play with after reading this.

    For your test, did you have it up as a flat top or more of an inverted V?

    Oops... spell check changed "tri-band" to "trigger-band" and I didn't notice...

    How much does the SWR change between set-ups? Can you be reasonably sure that what works in one setting will work in the next?

    I trimmed/tuned mine as an inverted V

    When I activated POTA, I again, set it up as an inverted V

    slingshot, fishing weight and line, shot over a tree, pull twine back through and raise the antenna.

    SWR was just right. I left the antenna tuner back in the vehicle

    .
    .
    Like any antenna, you could de-tune it by running 1ft off the ground, or setting it up with big chunks of metal in the near-field.

    It's not magic . . just a good dipole design.

    I, too, built one of these. I have a 60 ft pine in the back yard. Slingshot with 40 lb test used to haul it up. The SWR does change a little depending on how high I can pull it, but I can keep 90 degrees between the legs pretty easy. Highly recommend!
