This is pretty much how the ANTENNA WALL PLATE is connected to things.
A closer look at the TV WALL Plate connections.
The TV WALL PLATE used in most RV Trailers is not a BOOSTER AMPLIFIER as everyone likes to think. This is a POWER SOURCE to provide working DC VOLTAGE for the BOOSTER AMPLIFIER located in the base of the BAT WING ANTENNA. The TV WALL PLATE also is the power splitter for feeding both the living room TV and the Bedroom TV.
Assuming you have digital HDTV sets at both places now...
The only thing that disrupts reception for us when using the CABLE INPUT for both TVs is to be sure we have the ANTENNA WALL PLATE PUSH BUTTON OFF and the setup menus on both TV sets set to CABLE not ANTENNA.
We also have to RE-SCAN the digital HDTVs at both living room and bedroom everytime we change campground locations
