I just finished installing a Wineguard x2 dish and 2 Wally recievers. So here's the rub. The dish supports 2 recievers but BOTH recievers have to be tuned to a channel that the dish is pointed at. So ...
When you first set up the dish, you NEED to choose 2 receivers... this will put them in sync with each other.. instead if finding all 3 satellites, it will focus on 1, this will allow you to use to different revivers.
