So I keep getting put off by DirecTV. Its unbelievable, I don't know how anyone in my area can put up with this. Today's story was they didn't have the LNB for the dish they need to install. It is "back ordered nation-wide" and I have to reschedule. They tell me this over the phone from the call-center... So I make a few quick calls, buy my own AT-9 5 lnb dish for $50 and am trying to do the install myself. (Now they won't come out to the house because they don't have the SWM, which I don't even NEED since two wires are already run to my receiver...) First of many questions is... I have four outputs on the LNBs from left to right as your looking at it, and four inputs two labeled 13V and two labeled 18V. Which goes where?
