Just got DirecTV at my home (Main box + 3 others). I have a vacation cabin we use 100 miles away across the state line. The cabin has a directv dish already installed from the previous owner. If i take the main receiver to the cabin and hook it up to the directv dish there will it work as long as we arent using it at the main residence? If so, any set up issues to be bringing the receiver back and forth?
