    Can you receive OTA signal on a CB antenna. I seen something that you can connect your tv to a cb radio antenna. Anyone chime in on this?

    If you are close to a strong station, just about anything metal will work. :D
    Anything at a distance the answer is no.
    CB antennas are designed for a different frequency(~27MHz) than OTA TV.
    CB Antennas are designed for 50 Ohm coax not 75.
    CB Antennas are Vertically polarized(99% are anyway). Antennas on the TV tower are horizontally polarized.

    Any of the the three things above will attenuate your signal, some way more so than others. Guess what happens when you add all three together?

    ....then add in the fact that most CB antennas are junk, as they try to make them as small as possible. Some so much so, that they are effectively a "radiating" dummy load of sorts.

    Give it a try, you might pick up a local TV station at the lower end of the TV band but don't expect much. CB antennas are designed for the 27 MHz band, nowhere near where TV stations are located.

    I tried my discone antenna for OTA and was surprised to get some TV channels with it. Let us know how you made out, knowledge is power.

    I had a RS mobile CB antenna that was designed to supply the FM/AM radio as well. I also split that off to serve my scanner. :) But I'll bet the device to share the CB antenna with the TV was probably for the analogue days.

    I had seen something for sale at a shop to connect cb antenna to a tv. When the antenna was connected to a side mirror on a semi.
