RV Stereo Antenna cable issue

Generally the Stereo is NOT hooked to the antenna.. REASON.. Winegard, in theire infinite wiseom, or lack theeof.. designed the amplifier in the antenna so it would BLOCK the FM radio band... Please do not ask why.

Actually they do not "block" the FM, rather it is NOT AMPLIFIED. Overall the FM band is "attenuated" by about 20 DB since the amp has a gain of about 20 DB for TV bands.

It was done not because Winegard has a hate for FM users but to PREVENT FM interference from ruining your TV reception.

That is due to the fact that the FM broadcast band was right smack dab between analog channel 6 VHF Low (88 mhz) and analog channel 7 VHF High(174 mhz.

FM broadcast from 88 mhz to 108 mhz and many public service, Ham, business, fire, police, airplane radio bands from 108 mhz up to 174 mhz if amplified can easily overload a TVs tuner which will cause severe interference for the TV..

Not unusual for small antennas with a built in amp to filter down the frequencies of 88 mhz to 174 mhz since these small antennas typically do not have much gain by themselves..

For the OP, some RVs will have a small external FM "duckie" antenna on the roof or side of the RV..

If your RV does not have either the manufacturer may have simply run a short piece of wire out of the stereo around the cabinet. In this case you can add your own external antenna and connect it to the stereo for better reception.
