Cable connection not working

[Gary Heeb]

I have a Forest River FR3 with a cable port in the rear hatch. I hooked up to the cable jack at the RV Park with no signal to the 3 TV sets in the Motor Home. I then disconnected the cable line from the port in the rear hatch and connected to the outdoor TV. That worked, we had cable outdoors. Is there a splitter some where in the unit? Could it be defective? Anyone have this sort of trouble? Suggestions would be appreciated.

Thanks,
Gary
Always something to work on when you own a Motor Home.

Is there a selector box that says cable/antenna/satellite or something like that. You need to switch it to cable and perhaps turn off the antenna booster is there is one.
