TV hookup (antenna)

[N5PHT]

I am writing for a friend. Their RV is the Montana 3750FL and it is a 2011. He is having trouble hooking up a TV to the antenna mounted on the 5th wheel.

The TV in the living room has a panel next to the TV and it has 3 coax connectors and they are labeled BEDROOM TV, SATELLITE, OUTSIDE TV
and NO booster button there.

The TV in the bedroom has two panels next to the TV and one has a receptacle to plug in a 12 volt TV and the booster button and one coax with a label 'CABLE.' next to it is a panel with one coax and it is labeled SATELLITE.

There is a small jumper coax laying there in the area not connected. there is a 2 position splitter laying there also.

Now on the outside of the RV in the utility entry is a coax for SATELLITE AND FOR CABLE.

When he searches for TV nothing gets captured. I "think" he may need to pull off the panel with the booster (2 screws) and see if the over the air antenna is screwed in there - assuming it has some inputs there?

He would like to get the TV working in the bedroom and the front room.

Help appreciated.

The TV's should be connected to the "cable" connection, booster must be on for antenna use/off for park cable use, set TV to a appropriate input & scan channels.
If the previous owner has messed with the splitters or cables then the above procedure may or may not work in that case.
For just a few $$ you can pick up a cable toner to trace the cables & will save a lot of searching & aggravation.
