I am only asking about the coax in the trailer. Is the coax cable, or whatever it may be using, different for cable tv than the satellite coax. So, no. it doesn't matter if it's DirecTV or Dish. It's still just a satellite. I'm going to look at maybe running a new cable to the bedroom as a permanent fix but may try the wireless transmitter for the bedroom as I actually have one. But the one i have, the remote only works the DirecTV receiver, but I don't know if will work down the hallway. Worth a try though. Thanks everyone!
