    And sometimes they are just a halfwave of aprox 18 feet (give or take a few inches).
    Do you really think there's an electrically shortened cb 5/8ths wavelength mobile antenna out there?
    I'm not sure which poster you're refering to. In point of fact, a mobile antenna in the cb realm is akin to a dipole in electrical properties.

    As in a dipole affair, you can use a mobile antenna as one half the antenna while supplying the other half in the form of radials spaced around the mobile whip.

    Instead of reciting it all here, I'll refer you to the basic current flow of a dipole as referenced in your choice of publications.
    HAAT plays a part in several factors of most antennas. I'm not sure which factors you're pointing at.

    For practical & safety purposes I suggested not being too concerned with some "magic height" above average terrain because it takes a bit of empirical knowledge to ascertain which feedpoint elevation will assist in reaching the angle of radiation you desire.

    In most cases, the "magic height" doesn't hold true in all directions around the antenna & cannot be counted on to achieve the phase-added radiation you're expecting.

    I have a maco 5000 5/8s wave at about 73 feet to the tip of the antenna. I ran the imax and antron and concluded that nothing compares to the maco. It has 4-6foot verticals on it and they really helped me keep my RF power out of the neighbors houses. I had complaints at the fire department 1/4 mile down the street from me. When I set the maco 5000 up all my problems went away. Not to mention nobody around my town for about a 10 mile radius can key over me. I run a cobra 2000gtl with a 350 watt palomar magnum. Like to talk a lot of skip on the weekends. They maco will run you a little more but it is well worth it. Mine costed I think 150.00. I only run aluminum antennas. If you use a magnet mount antennae for a base antennae then you must use a sheet of galvanized steel under it or mount it to a gutter on the eve. This is not a good recommendation to use a mobile antennae for a base. If you dont get a good match (which is very hard to do.) then you will blow the finals and receive diodes out in your radio of choice.

    imax 2000 would be my choice
