TV Antennas on Rear Window Cause Problems ?

I don't see any reason why the radio would suffer any signal degradation. You want to be sure that you don't lay a conductive surface over the printed antenna "lines", though. And don't attach anything to the rear defroster grid area.

In my experience they are not quite as omnidirectional as a whip antenna (or they exhibit a bit of directionality), but the difference is not really not of significance. Be sure to ground the antenna exactly as the manufacturer says or the signal will be highly degraded.

Is this an aftermarket antenna?

thanks yes it's pyle plvwan6

OK, thats the one with two sets of wires. Where do they have you install the antennas...not the rear window I hope. It really isn't a diversity antenna, but for $29.99 you could not expect one. Also be sure all connections are good and that you have a solid ground.

John, Yes, instruction says to mount the bases on REAR WINDOW - upper left/right corners so the antennas lie along the top/left/right edge of the glass.

So mounting on rear windows is not good for what reason ? thanks

Should not be a problem, other than appearance. The amplifier should be kept as far away from the other atnennas as possible.

You can always look into a product which will take your current antenna and split it out for the radio and the tv and not have to add another antenna at all and stick an amp on it if you want.

these guys carry that sort of thing.
