    Does anyone know where I can purchase a powerline antenna? These used to
    be very plentiful. They seem to be very hard to find these days though.
    Could anyone point me in the proper direction?
     
  2. Perhaps because they were marketing gimmics that never really worked?
    In the rip-off section next to the snake-oil?

    These never worked very well. It is another gimmick to make people spend
    their money. For a local inside antenna, nothing beats a simple pair of
    rabbit ears.

    Nobody sells them because they're junk and never worked worth a crap.

    Uhm that's not entirely true I am *not talking about the plug your tv into
    the wall outlet type of powerline antenna. I am talking about the type of
    antenna that you could hook up to a powerline and examine pn pg ng
    individually while having your receiver hooked into an outlet. It may or
    may not have some attenuation switches as well to keep you from blowing
    the front end of your receiver up. I am well aware of the limitations
    surrounding powerlines. I would be using this for experimentation. The
    powerline antenna would primarily be for the protecton of the receiver
    connected to the outlet. I really don't care if there is static. There
    used to be a few companies that sold such boxes, but i have not been able
    to find them.
    I appreciate the help everyone has given though.

    manaen:
    Our local, small town power company just uses cheap AM radios that have a
    signal strength meter to look for noisy power lines, bad insulators and
    such.

    That is an interesting solution for stuff that radiates out into
    freespace. I am going to have to go dig up an old am radio and check
    it out. What I am really interested in looking at is the carrier current
    communications that are on the line and not radiating out into freespace
    (I know no matter how small a signal on the line is there probably are
    some freespace emanations). Guess I need a box, with a powerline input and
    bnc output that blocks AC voltage, DC voltage, switches between PG PN NG
    and can attenuate an rf signal from 10 to 30 dbm. Almost forgot, a 60hz
    comb notch filter would be nice as well. I could "hack" together a
    solution but I am pretty sure others have done this already.
