To hook up 2 Dual-Tuner Receivers. You will need a Dish Pro Plus Twin and Dish Pro Dual hooked up to the DISH 1000. You wire the Dish Pro Dual (129w) to the 'In' port of the Dish Pro Plus Twin (119w/110w). Then with 'Port 1' and 'Port 2' of the Dish Pro Plus Twin, you run cable from that to the Dish Pro Plus Seperators which connects to your Dual-Tuner receivers. Got it?
