Exterior Coax Connection Not Working

Any ideas on what could be wrong?

Sometimes its easier to simply run a separate coax when needed at the outside location. Screw the coax into a source that works and watch the game.

If you are looking for something to do ......
Double check the original location where the tv worked before you moved it.
Make sure the other location that previously worked is still working because the roof coax can become loose due to over the road travel or the up/down movement of the antenna.

The coax cable located in the outside compartment should then be checked if that's the location where it is not working.

coax often becomes unscrewed behind the coax connection for the tv due to being compressed inside the relatively thin rv wall in combination with the movement of the rv bouncing down the highway.

Unscrew the 2 screws holding the plate cover and check to see if the cable is screwed on tightly.
If you buy a tester you can see if the signal kicks on when you jiggle the coax at various locations.
You can buy inexpensive coax testers at places like H.Depot for $15.
Check the coax cable to see if it has a connection. If not trace it to determine where the break is. They use splitters inside walls etc .
