New motorhome hooking up tvs

I have the King satellite antenna for Directv. The Winegard satellite antennas have a separate power cord to get power to the antenna so it can move. I think yours is like mine since they are both made by King and do not have a separate power cord to the antenna. The satellite antenna actually gets the power to move/turn to locate the satellites from the coax from the receiver. After much research, I learned that mine only works when the coax from the antenna is plugged directly into the receiver. If I plug it into the fiver satellite connection it will not work because the voltage will not be passed through to the antenna. I have to take the coax attached to the antenna and pass it through my slideout seals and plug directly into the satellite receiver. It's pnly about a foot or so of coax that can be seen but rarely is noticed by anyone.

Yours may or may not need to be done this way, but mine does so it may help. I've always just been content to get satellite TV on our main TV and never worried about the bedroom TV that we hardly ever use. Good luck.
