    Hinges absolutely can't be relied on to provide good electrical contact. Sliding contact basically equates to NO contact.

    THAT makes a difference! :)
    I've never experimented on anything above 440 MHz. I'd take a look at commercial antennas, see how they do it and try to copy it.

    Two questions for you:

    1. Are you licensed? If so, what's the call?*
    2. When you refer to "your area", just what "area" do you mean?

    Most MFJ analyzers don't cover 1.25m, but those from RigExpert do, and pretty well. The 269C I once used above HF had no noticeable degree of stability. An icy stare from me seemed to make it think...
