Sensar Lead in cable and power

[RVhiker]

I have no TV reception. There is not 12 volts from the lead in RG-59 cable at the roof antenna. There is 12 volts at the antenna cable connection at the Winegard power supply. The lead in cable at the power supply is RG-6. Somewhere the RG-59 and the RG-6 must connect and I suspect that is the location of the power loss.

Does anybody know where generally does Jayco interconnect the RG-59 from the antenna to the RG-6 that goes to the power supply?

Here's the answer, at least in the case of my 2011 Jayco fifth wheel.

The whole story: No TV. One issue is that Jayco used RG-59 lead in with a steel center conductor, copper plated. The copper eventually corroded away at the connection to my Sensar antenna and rusted away. I found this when checking the no TV condition. The remains of the steel center conductor was rusted into the connection on the antenna and could not be cleaned up. I got a new head unit, installed it, no TV. And no 12 volts at the antenna, but 12 volts inside. Ran new RG-6 through the antenna into the roof of the trailer and connected it to a temp RG-6 cable connected to the power supply and got TV.

I rooted around in the ceiling with a wire with a hook on the end and found RG-6 cable. I concluded that cable came from the power supply, cut it in half and tested for 12 volts; I found 12 volts on one side of the cut. I put a connector on the hot side, connected it to the new RG-6 I ran in from the antenna, and had good TV.

All because Jayco decided to use cheap copper plated RG-59. But hey, it even lasted through the warranty. Although if Jayco had used solid copper RG-6, the problem would not have occurred.

Thanks, Jayco, for more crap.
