All the LNB's are the originals that came with the dishes so yes we're using a DirecTV LNB to pickup 61.5. So it looks like I'll need a dish pro LNB but what exactly do you mean by bracket? Is it that just the arm? BTW, Thanks for the quick response and the kind welcome.

My Dad's having problems setting up his system to receive signals from 110/119 and 61.5 at the same time and neither of us can figure out why. We're both a couple of noobs so there's probably something basic that we're overlooking. He has a dish500 (dual LNB w/ integrated switch) which works...
