My setup for my new 722 system: TV1 is downstairs and TV2 is upstairs. The remote for TV2 only works in certain areas upstairs and makes changing channels difficult. The installer assumed that the walls of my "well built house" was causing problems with the UHF signal. He moved the TV2 antenna upstairs but the splitter caused too much of a signal loss. I've done my own experimenting and have determined that my Samsung LCD TV, TV1, is the problem. When it's turned off, the TV2 remote works perfectly. The antenna on the back of the Dish receiver is right next to this TV. So should I extend the antenna with coax so it's a couple of feet higher than the TV, get an attenuator, or is there another preferred way to do this?
