I have a Winegard Carryout (the bigger version) and previously had a plain, ol' dish, which made me CRAZY. The Winegard is a wonderful improvement. Wish it was smaller, though.
I just take a receiver from the house (Directv) and it works fine. I am not fussy about having HD in such a tiny trailer!
I understand these days, that certain new receivers will not work properly with the Winegard. Here's a link to Winegard's site that tells the model numbers of compatible receivers for each of their antennas:
