    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.

    "High frequency" is the general term for frequencies between 3 MHz and 30 MHz. At these frequencies, a few (or even several) millimeters won't matter much. What frequencies/bands do you have in...

    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?

    *If you're not licensed, listen all you want on the...

    Experiment and study what works and what doesn't. You'll need some test equipment and plenty of writing stuff for recording dimensions, frequencies and such. In general, a multiband mobile antenna...

    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...

    A digital meter WILL usually be more "precise". This term refers to repeatability of a reading. Analog meters generally have mechanical movements. This introduces friction and...

    This is where someone suggests a known-good dummy load of proper power rating. Connected in place of the antenna it'll show you a lot of things.
