On my 2011 Greyhawk, I Have Direct tv. I have the sat antenna connected to the "sat in" connection on the Direct TV receiver. I split the "Sat out" signal through a three splitter to the main tv, the br tv, and the outside tv outlet. All three tv's work, but since the DTV box sets the channel, all three tv's show the same show. I send the Winguard antenna signal through the "antenna in" connection o the DTV receiver. The DTV box has to be off for the Winguard signal to get to the tv's with the DTV rceiver I am using. I had an older DTV receiver that was set up this same way that allowed me to watch antenna on br tv and DTV on main tv, but the newer receiver will not allow this. (Direct TV receiver has to be turned of for antennae signal to get through with the newer receiver.)
All the cables are coax. HDMI and/or AV cable setup will be different. Hope this helps.
