    thanks i didn't see anything about a resister in the advertising
    if so that just makes it the piece of crap that icom sells for a broadband antenna
    too bad , i have access to ss cable i thought it would make an interesting project to build

    You won't. It's implied by the simple fact that the claims are 2-30Mhz @ 50 ohms, fed with coax. That's simply not possible without a "matching network" at the feed-point, based on what the 912 looks like. The only thing (IMO) that could present that impedance over that wide a range of frequencies is a resistor. The second hint is the different models with different power ratings. Larger resistors for better heat dissipation at the higher power levels.

    Icom, Yaesu, B&W, and several others.

    A simple 135 foot dipole, fed with ladder line directly to a tuner, is a perfectly fine "broadband" antenna and will be more efficient than the 912 overall.

    i know the length of 135 ft dipole would put it outside my property line
    i just have to go with a folded dipole with about one foot spreaders
    i am still trying to find 14g ladder line around here

    How much room do have?

    Why? I run a KW into 18g ladder line.
