I just got a Winegard G2 to use with my new Class A. I like it, but there are a few drawbacks. The most annoying is that it likes to have a good coax feed directly to the Sat box. My Winnebego apparently had degraded coax from the service bay to the cabinet where the Sat box goes. I ended up running a new, quality cable from the cabinet and it now works great. There is a recommendation that the overall cable length not exceed 50 feet. I have not tried a longer cable yet, so I can not answer to that.
I used the tripod-Sat dish for years. Bulky to store, timely to set up, BUT you could set it up with 100 feet of coax.
Hope this helps
Bill
