Sorry guys if I have caused confusion. Maybe I can make it a little clearer.
I use Direct TV service and will use one of the receivers out of my house. It is a HD 24.
I only want standard definition in the motorhome. Do not want HD.
I will use only one receiver. I understand that I will only be able to watch the same programming on both TVs when using satellite. Thats fine.
This is a brand new rig so I have never attempted to do one thing as far as for as changing from cable to over/air. Simply switched TVs on one time just to see if they would turn on. Thats it.
Will not be using the roof satellite wiring so am not interested in that.
As I attempted to state above my goal is to be able to pull into a campground and hook up their cable service and also set up the satellite and hook it up also so that I can use either of them or the over/air without going out and connecting and disconnecting. The connection for the cable is already there. I will need to install one for the coax from the Carryout to hook to and the wiring to get it up to the receiver in the entertainment center.
Once I have done that I know I can change back and forth from Cable to over the air by turning th amplifier of and on. Just need to know how i can incorporate the satellite receiver into the mix so that I can switch to it if I desire---again with out connecting and disconnecting coax cables each time. Is it possible or am I dreaming?
Thank you guys very much for your responses and I apologize for the confusion.
