All these different switches are driving me nuts. OK, I have two legacy LNB dishes for 3 satellite locations. I currently have them going to two sw21's to feed two receivers (301 and 6000). I think I figured out that to add one more line for a third receiver (actually a second input to a 921 that replaces the 6000) i'd need a sw64. I thought I had bought one on ebay but the guy emails me and says it's actually a sw44, he messed up the discription. This won't work in my situation, correct? I need the sw64 because of the second dish. Also, what's the deal with the power inserter and adapter. I would assume that they are neccessary, but quite a few of the auctions on ebay don't include them. OK, venting over, back to looking for a sw64 (assuming that is what I really need)
