Please forgive the ignorance of this question. I've been out of the loop on Dish network equipment for a few years. The last time I installed a Dish Network system they were using the 522 and 322 dual tuner receivers. At the time they had a Dish Pro Plus seperator. My question is will the seperator work with a brand new triple LNB HD turbo dish? I'm not sure the model numbers of my LNB or dish but I have one vip 722k receiver and only one dual coax coming from the dish and I'm not sure how many outputs the LNB has on it and I want to add an old 301 receiver to the system for an additional room. Is it possible to use a seperator for the third tuner?
