I recommend the Winegard Pathway X2 for Dish TV. I've had mine for several years and it fits all of your listed requirements. Easy, automatic set-up. We've never used the eastern arc but it's advertised to do so. It will operate with two receivers but only one receiver controls the position of the antenna. The antenna moves slightly if the channel you've selected is on a different satellite than what you were watching. That could interrupt the channel the second receiver is "watching". The only issue I've had with it is when we've experienced freezing rain; the ice will collect in the track and prevent its movement. It's light and doesn't require a perfectly level surface for operation. I did make a short (5 or 6 inch) table for it to sit on. When I stow it in the front basement of my RV I just turn the table upside down and set the antenna inside the legs. Hope this helps.
