I'm planning to go with just the dome for now. Do I really need 2 antennas? Is there an advantage of one over the other?
Well, you lucked out -- that "pop up" dish is a Winegard Travler, probably a DirecTV SK-3003 or SK-3005. I'm pretty sure your Travler is not the newest DirecTV SK-SWM3 because you found an 8-channel SWM switch in your coach.
Anyway, spend the money to convert your Winegard Traveler to a DISH version. However, first check here
to see if that's even possible.
A DISH Travler will allow your Wally receiver to see all three DISH sats at once. In fact you could connect 3 Wallys to a DISH Travler.
The dome? You don't need it.
