Why can't you use your own sat for the bedroom unless you only have a single receiver. If you have a dual receiver you can send the signal back to the bedroom TV. I don't have mine on the roof so my sat signal comes in the rig on the usual connection on the side of the trailer where it goes into the sat receiver. I have a TV 2 connection on my receiver where the signal comes out of the receiver and I send it back to the bedroom TV. Just remember to shut off the little green light in the bedroom closet. This way your over the air TV antenna still works, just have to turn on the green light and if you want to use cable just have to replace the cables coming into the rig and going to the bedroom TV with the 1 ft jumper cable. Sorry my schematic is a little rough lol lol -----now this way only works if you have a dual receiver so if you have a carry out or your service it thru Satellite To Go that uses a 211 receiver it won't work.
