So as everyone saw my other post my grandpa wants to do dish without paying. He decided he will pay 72.99$ a month for 1 room and all the other roooms will just be receivers without service with ota adapters. But I am wondering which receivers would be good for these rooms. Vip 211k? 211z? Wally? Hopper duo? Also dose the 211z support the ehd like the Wally and 211k? And dose the 211z also support the ota adapter
