    So im going portable with my KX3, plan to purchase KXPA100 early next year. Currently have a 20m vertical sota antenna. Plan to make a 80m dipole fed with 450ohm to carry along.

    What balun ratio would i need? Some locals say 1:1, others say 9:1...

    What other odds and ends would you carry?



    Minimal pack would be just KX3 and some sort of light weight vertical.
    Max pack would be in a dedicated day pack (KXPA100, battery, ect..)

    The KX3 and KXPA100 would be my mobile setup with some sort of screwdriver antenna...

    I have a KX2 for my SOTA adventures. I use a few antennas but the best is random wire, 58' with 13' counterpoise. Both are elevated almost like a "v" configuration. Internal tuner tunes 10-80 metres.

    I totally agree... but i just love resonant antennas
    Thats why i have a 20m vertical sota antenna that weight under 1.5 lbs, but i love lower bands..

    If it's resonant antenna, then really no need for a balun, in my books.

    Then ground mount the balun, but if your KX3 has a tuner, I would try that first.

    For the pack antenna with ladder line, I would just forget the balun unless your field testing with the antenna shows that you absolutely need it to get a good match. I'd start with a BNC/Banana plug adapters and let the internal tuner (which is amazing) do its thing:

    https://www.ebay.com/itm/BNC-Male-P...pid=16024417993&hash=item2cd932d69d:rk:1:pf:0

    If that doesn't work to your liking, then I'd consider the Buddipole Triple Ratio Switch balun, which is small and lightweight and also has BNC connectors. It switches between 1:1, 2:1, and 4:1 ratios and will do the trick if needed. I have one of these in by toolbox and find that it really is a nice accessory.
