Hi there. Just registered to this site and have had Dish for going on three months. I currently have At180, 4room with a 522 and 2 311's hooked up to three sat locations (119, 110, and 148). I have two dish 500's. One with a Dishpro Twin LNBF and one with a Dishpro dual LNBF and going through a DP34 switch. I would like to know what would be the easiest or cheapest way to add a fifth receiver to the system. I know I could add another DP34 and do it that way. Is that the only way, or is there other ways I can do this. Thanks.
