I apologize if this is found elsewhere, but I just found out my 921 is in and I'd like to get it up and running before the 2/12 install date for my new 510 and extra dish for the locals. Originally I was told it would be a couple of weeks at least before the 921 would arrive, so I had given up on HD superbowl. Now hope is very much alive. I currently have a Dish 500, 2 dual LNBFs, and an SW21. I have 2 feeds to 2 rooms/receivers. Both receivers are older Phillips models. What can I do at least temporarily and, hopefully cheaply, to get set up for the 921? Any suggestions? I have an easy run to the 921 location through the unfinished basement. If I got hold of another SW21 is it possible to cascade - a term I have read on this forum, but am not sure of as applied to signals from the LNBFs? If so, exactly what is the logic for doing that? Also, what grade/spec cable is req'd, exactly? Detailed explanantions are most helpful and appreciated. Apologies if this is old hat to many of you, but then, taht's why these internet forums are so useful to the rest of us out here. Thanks.
