I don't know but if you have a winegard antenna on the roof and you put a winegard tv-outlet (this is for OVER THE AIR only, not sat) you can then put another "outlet" right beside it for sat
Hook up is like this... Antenna to Winegard outlet (Which is also the power supply for the antenna's pre-amp) 12 volts to back side of winegard plate via fuse.
Winegard outlet to sat receiver's "ANTENNA" input
Sat Receiver RF-out to television or to splitter (more in a sec)
Sat dish (Be it rooftop or tripod) via RG-6 cable to Sat Receiver LNB input
Now, if you have two tv's it gets tricky Winegard makes video switchs (very nice) or you can just use a pair of A/B switches from Radio shack but if you never want to watch OTA on one and Sat on the other there is an easy way
You make the 2nd plate a dual feed through, RG-59 from the receiver's RF out goes to one fitting which then goes to the common input on a splitter, The outputs of the splitter go to the remote TV (1) and (2) back to the panel, the splitter hides in the wall (No rat's nest of wires) and the other Outlet on the plate goes to the TV
