Thanks Gerald,
Background:
I have the ceiling swing down TV which puts my first Dish Receiver in a side cabinet over the passenger side couch/recliner area. The second satellite receiver is in the rear closet. I have no VCRs in this coach and two DVD players. The original VCRS were removed. The DVD players are located where the satellite receivers are, One up front and one in the back. The satellite system is original and is in need of upgrade which is my current project. I plan on using a Dish 722 unit with dual tuner and that install will necessitate wiring from the rear closet for distribution of the signal. I'm not worried about that portion. It will have to have new HDMI cable or HDMI via RF transmitter and receiver to the front and composite video cables to the rear TV. There is no overhead cabinet in the front of the coach that will handle the depth of the Dish 722 receiver.
Problems/Questions:
Regarding the terrestrial signal that comes from the roof antenna and the cable system input, I was wondering where they combine with a coupler. I get a decent signal to the front TV with both sources but it is weak and I get digital distortion with the rear bedroom TV. I know the coach is wired with RG59 and digitally there is a lot of loss with that cable. I was going to add a distribution amp to boost these signals and see if I can eliminate enough loss to make the signal at the rear TV equivalent to the front TV. Once that is done I only have to worry about the 722 output which I would not want to degrade using coax anyway.
The 120V outlet used for the overhead TV, is it on the driver side or passenger side? I need a power source for the distribution amp and I am not sure how to get access to it. I have a small front cabinet on the passenger side next to the TV that houses the antenna power switch. I'm hoping the outlet could be reached from there if I pulled it. I know your arrangement is different from mine but how the RF cables and couplings are arranged in the front overhead area on yours may provide me some insight. I'm hoping that the cable TV input from our facilities panel also gets routed up into that front overhead area for distribution also. Thanks again for any insight on this.
Before I am done, I am sure that I will wish that I had longer arms, better eyes, and the agility of a Cirque Du Soleil performer....
