The analog IRD, a Houdton Tracker 70, moves the 10' antenna and powers the LNBs. The Fortec uses the LNBs for FTA signals.
I can't watch
C band and DVB at the same time. The "Master" usually controls polarity, but I have a relay so that when the Fortec is powered on it controls polarity. I have another C Band IRD from Ebay, and I'm setting up another BUD to free up my C band receiver.
