Cable TV

2018 Four Winds 31 Y, recent purchase. Can’t locate cable box or splitters. Antenna for air channels isn’t wired into TV either. Tech trying to fix unsure of where components are. Working park cable connected to outside receptacle on rig yields nothing. Any thoughts? Thx.

Here's my thought: find a new tech.

RV and OTA/cable antenna connections on RVs hasn't changed in decades.

Your OTA antenna has an amplifier in it that requires 12 VDC to power it. This 12 VDC is "injected" into the COAX cable going to the antenna by a power injector circuit board which also acts as the OTA/Cable selection switch as well as an output splitter. There may be an additional splitter downstream of it.

This circuit board is usually behind a wall plate that has a small push button switch and LED on it. It may also have a COAX connection and/or a 12 VDC cigarette lighter style power jack.


The power has to be ON for OTA antenna operation and OFF for cable use from the external cable connection jack.

Also any time you change locations or input (antenna to cable or vice versa) you'll need to go to the TV setup menu, select appropriate input & scan the channels.
