Just bought a new motorhome with a Tracvision R5SL antenna. I have five Sony Bravia TV sets which can each receive separate channels with a coax connection from an OTA antenna. I would like to install a satellite receiver (either DirecTV or Dish, I have DirecTV at home). I understand that I cannot receive HD from DirecTV on the Tracvision antenna. I would like to receive satellite on two of the TV sets. There is only one coax coming from the satellite antenna. There are no wiring diagrams from the coach manuafacturer. Where do I start, what hardware, etc do I need to accomplish this. Is it possible to use a spare standard definition DirecTv DVR with two inputs? Please help me get started or point me in the proper direction!!
