Just got Dish. Have a hopper in house, have a Wally in one bedroom. It’s programmed to work in the house with a seperate hook up to satellite. Have a second Wally in motor home. Tech programmed it to work with original coach dome satellite antenna. Told me might not get every channel with Orem dome but probably get 90%. I could take Wally from house and put in motor home, but would have to change programming every time I switched it. I just bought the second Wally and activate it when we leave the house. The hopper works totally independent from the Wally. I got all from an independent satellite retailer who sell and installed nothing DTV and Dish. He installed everything. Never called I-800
