Is there a wall plate in your RV with an antenna connection, a 12 volt outlet, a switch, and a light?
Turn the light off for park cable
Most people call that the antenna pre-amp. it is not
it is a power inserter (The pre-amp is in the antenna)
and a switch"
NOW if that does not work "Pull" the thing out (two screws and remove it from teh wall)
Should have 2 or 3 cables hooked to the back
Looking at the back witht he outlet at the top
1: Over the air antenna, 2: park cable, 3: TV-2 (Output to a 2nd TV) and optionally 4 TV-3
Home was where I park it. but alas the.

after a semi "nicked" it. Still have the radios
