Batwing Antenna

Could have damaged the cable between the roof and the antenna mast.
Could have damaged electronic booster in the head.
Take cable loose at the antenna head and retest cable

Made me think of one of my trips going through Smoky Mtns… We had just left ELKMONT CAMP heading for Townsend and found an antenna laying in the middle of the road. It was one of those BATWING type... This was just past a pretty sharp turn around some low over hanging rocks. I picked it up and laid it in the back seat of my truck... We went a bit farther up the road and here was a motorhome pulled off at a pull out with driver outside looking at his motorhome... So I pulled over too and asked if he was missing an antenna... He was shacking his head for yes so I handed him his somewhat slightly bent antenna... Told him it was laying in the middle of the road a few miles back just after the low over hang haha... It didn't look like it was damaged all that much. Bet he got it back up and working again...

You read about this all the time of RV'ers coming up with ideas to remind them to check for the still raised antenna before heading out...

Usually there is a connector set where the cable hits the roof. Now depending on who built your RV it may be sticking up through some caulking or it may be buried under a clamshell cover. I had to replace both cable ends and the Barrel (Double female) connector on mine... I used weatherproof Compression ends on both the cables (Roof to antenna and roof to switch plate) and sealed it all up good when I was done. I like those compression connectors. they hold nice and strong. not like the crimp on jobs the factory used (AH-AH-AH-CHOO and they pop off).

I would suggest that your first trouble shooting step would be to run a new coax from the antenna directly to the Antenna input on the wall mounted power supply. This will give you a definite yes or no as to whether the cable is the problem or whether is could be the a problem in the head or downstream from the cabling. We too often assume that a problem was caused by a recent event when the problem turns out to be completely coincidental.

Did you just forget to push the little button on the antenna box??

Splitters might show a short to an ohmeter.

Did you re-scan with park cable settings on your tv? It is so easy to forget a step.
