Most of those WALL PLATE ANTENNA PANELS are not BOOSTER AMPLIFIERs. This is where the BOOSTER AMPLIFIER DC POWER control circuits are located.
Their function is send up 12VDC to your OTA ROOF MOUNTED antenna where the BOOSTER PREAMPLIFIER is located. This has a push button on the panel and when you push-in a switch you can see a small LED light come on telling you 12VDC is going up the RG cable connected to the roof OTA antenna. This circuit also BLANKS the cable connection coming from the campground CABLE CONNECTION on the outside of the trailer.
This is neat pictorial on how the ANTENNA WALL PLATE is connected.
Not a whole lot that can go bad with the antenna wall plate panel... Problems is most often the PUSHBUTTON is pressed-in when trying to use the outside CABLE TV CONNECTION or a bad F-type cable connection, or the 12VDC Connection coming from your 12VDC Power Distribution Panel is missing. If you are camping off the power grid the 12VDC battery may be discharged or switched out.
This is the way my WALL MOUNT ANTENNA PANELS works at any rate...
