I purchased a bsc-621. Im trying to install it on a 8.5 BUD.....I removed the old feedhorn and lnbs. so now I have the arms bolted to the scalar ring. How far down does the bsc-621 need to be in order for it to work? I get about 70 signal out of KU band but 0 signal out of
C band.....I have a fortec star receiver so what settings do I need to set? I have both C and KU seperated from the dish coming down and connected to a DISNQC switch next to the receiver....does this make a difference or im better off combining both signals from the BSC-621?
