[QUOTE=Franswa;713233]around that time (I have a 97 model year 17center bath) BF had "built-in" antennas....a wire (orange) buried in the roof coupled with a 12V signal amplifier....
reports of their performance were mixed...I tried to get mine working but gave up (I don't watch TV while camping anyway)...there is a warning sticker letting people know NOT to test unit in some manner I don't understand...I assume someone before me did that because I never got the thing to work (I was only trying to get everything in the trailer working like it was when it left the factory)
so for now I just left everything alone and only use the 12V cigarette plug included in the fixture (it's very handy where it is located)....
It looks like we have the same set-up. The notice on the cover of the selector is something I haven't seen before.
