I found an abandoned PrimeStar dish minus the LNBF. I would like to mount a DirectTV LNBF and use this dish with my RCA 38310, which has a built-in DirectTV turner. I am only interested in HBO HD for $13 a month. I have installed a BUD, so I think I could handle the aggravation of a jerry-rig. The dish has some degree markings, but I don’t know if they need any adjustment for the offset of the disk or whether they are the same as a C band dish. This dish is wide and big, has anyone put a bracket on it to hold more than one LNB? Thanks
