From my post on another forum:
I installed a Dish Tailgater satellite not too long ago. I was hoping that I would be able to watch satellite TV on any of the 4 TV's (living, garage, bedroom, outside) without major wiring modifications. I knew I would have to watch the same channel as the dish itself is limited. I also wanted to be able to watch antenna programming on any TV. The trailer was wired to do exactly what I wanted. I connected the coax from the dish to my connection outside the trailer. I connected the receiver box to one of the connections on a wall plate that had two coax connectors on it. I took another piece of coax and connected it from the "out to TV" on the receiver and connected it to the other connection on the wall plate. The TV in the living area was connected from the receiver using HDMI. What all this did was allow for antenna TV on any TV. The living area TV can watch either one just by switching inputs. The other TV's work by turning off the antenna booster, switching to channel 3 and use the Dish remote to change channels. I have a couple more things to do.
I also built a tilted shelf so the Dish receiver would fit in the cabinet. Without my modification, the receiver box is slightly deeper than the cabinet. This tilted shelf method works great. I also bought a IR to RF remote control device on Amazon for ~$30. That way the receiver stays in the cabinet and I can use the Dish remote at any of the TV locations. I even set the dish remote to work on the TV outside to operate the volume, etc. As a bonus, I tried it on the TV in the bedroom and it operated that one as well. No need for two remotes for those TV's.
I did not have to change cables at all.
