I currently have 2 811 receivers and I would like to add another reciever to my account. My two dishes are pointed at 61.5, 110, and 119. My quiestions are since I will have 3 sat locations and 3 recievers plus an ota how will the installer combine these together seeing that the dp34 switch has no ota port. By the way I have 1 dp twin and 1 dp dual hooked up now with two dp 21's connecting them. Also hom many hd recievers can you have on one account.
