Here is my issue... I have DirecTV with 4 Receivers. 1 of the receivers is hardly used. I have seen people with Dishes set up at Marinas on Boats, at Camp Sites with RVs and stuff like that. They just set up a dish and hook up the receiver. Can I do this at my summer home by setting up a dish and hooking up the receiver from my other home? I was told by a DTV person that it can be done. You are supposed to just use the service only at 1 home at a time. What if I have a house sitter and they turn on the tv while im watching tv at my summer home? This would mean 2 dishes would be going at the same time getting signal to receivers of mine in 2 seperate locations. Is this a problem? Thank You
