Just an update to all who've been following or contributing to this topic...
I returned the Winegard X2, and chose to mount a Winegard Trav'ler to the roof. Busy schedule means a May install date, but I've learned much since my initial post, and feel this, for me, is the way to go.
I've also figured out the satellite access issue, recognizing this is independent from the cable I first confused with it. Further, I've learned my rig is wired for satellite on the roof, so install shouldn't be an issue. When Wally's connected (2), everything should go smoothly, once connected to TV's. Audio/Video component dictates source, and figured out the OTA/Cable switch. Access to run coax to TV's is limited, but of course, necessary. Going to have Dish service soon, before sat antenna install, so am feeling more confident I've grasped the basics better than I had initially, but then, isn't that the benefit of having a resource like this forum?
Solar install next week, but that's another thread...
