Our motorhome came with one of these, and inside there was a monitor that showed the elevation. We used it for a couple of years after we have DirecTV installed when I didnt feel like setting up our portable Slimline-5. This dish will only get SD tv, at least for DirecTV. I didnt realize there was still a market for these, so when we had a Winegard Trav'ler installed, I sent the Winegard RM-DM46 off to the dump. By the way, the elevation monitor is still on the ceiling of my motorhome.
