I have an 08 Jayco Jay Flight G2 which I bought a year ago. On the 3 times I took it to a campsite with no cable TV hook up I could not get a TV signal using the antenna, this last time I even bought a piece to put on it made by Wineguard to boost the signal, still no signal , where they had cable I had no trouble. One of the guys with us had a Jayco trailer and he had the same problem when he first got his trailer and he said he could fix it for me. We ran a cable straight from the antenna to the TV and I got a signal so we knew the antenna was O.K. Then we hooked up 1 wire at a time from the back of the splitter direct to the TV until we found out which one was the antenna and the TV worked fine. We did the same for the other remaining wires and now it works great.
Well it seems Jayco has wired it wrong at the splitter box. They had the antenna wire going to the bedroom TV from the splitter and not to the center of the splitter. They had it wired the same way on my buddies Jayco. So if your having a problem with TV from the antenna you might want o check it out.
