I looked over everything in the house tonight and here is what I have:
There are two wires coming out of the wall. One goes directly to the HR34. The second wire goes to a SWM power inserter (to the "power to SWM") then a coax out of the "Signal to IRD" that goes to a DECA. In this case it is a DCA2SR0-01.
I will climb up on the ladder tomorrow and see what I have for an LNB.
