  1. With the advertisements regarding the upcoming conversion to Digital
    TV, they always mention that you need to be sure you have an antenna
    suitable for DTV reception, and sometimes recommending a 'smart
    antenna.'
    I presume any antenna currently available for purchase is already DTV
    compatible.
    What is the difference between one that is compatible, versus one that
    isn't? TIA

    Nothing. Any antenna that will pick up UHF frequencies is "compatible"
    with DTV.

    Also take a look at http://www.tvfool.com for a wealth of info regarding
    the direction and the estimated signal strength of local TV broadcast
    stations from a given receiver.

    In general, if your antenna was sufficient last spring it will be sufficient after Feb. 20th.

    That said, I "lost" the ABC network when the local affiliate began transmitting DTV. Neither of two
    converter boxes would find the channel. I thought they'd gone off the air. What happened is that
    the station transmits DTV on a higher freq. than the other three local stations, a freq. that
    requires a newer, hi-gain antenna. The UHF loop/rabbit ears I've used for 30 years won't pull it
    in, while they do pull in the other three stations. I can see the towers of all four stations from
    my yard, so it ain't distance that causes the problem.

    Maybe, depending on your exact location in relation to the station
    you're trying to watch. I'm finding that a *VERY* simple dipole (As in,
    strip back 4.6 inches of braid at the end of a piece of co-ax, then fold
    the stripped braid and the center core (no need to strip the center
    insulation off the core) to form a T shape) tossed out the window is
    sufficient to get me all the signal I need, despite my location being
    considered "fringe" or "extreme fringe" for most of the channels
    available here. All but three of the ones that I'm supposed to be able
    to see come in fine (and those three I can do without - I don't speak
    spanish or korean, and I can cheerfully live without preachers trying to
    tell me about their imaginary friend in the sky, so not having them come
    in doesn't bother me in the least.)

    Note: 4.6 inches was chosen to be in the center of the frequency spread
    for the group of channels I'm supposed to be able to get - Your group of
    channels may need a different length to match the frequencies your
    stations are on.

    Not all stations are converting to UHF, the high frequencies ,
    channels 7 -13 are also going to be used, as far as I understand,
