Hi All, Newbie here. Is it likely that I would be able to recieve signals in the mid to upper 90's on my HDTV reciever ( Sony SAT-HD300) for sat's A & C and get zero signal on Sat B. On initial set up and alignment, I did recieve a signal from B briefly, then nothing. A tech at Direct TV said it would be unlikely I'd get that good of a read on A & C and nada on B. Likely equipment malfunction. So I go out and buy a 2nd dish and use that triple LNB. Same problem. The first dish is a Aspen Eagle and the second a Funai from Best Buy. Any clues as to what's up would sure be appreciated. Yes I'm a rookie at this. Thanks!
