I have recently aquired two "Jack" Antennas from King Controls. I used one to replace a huge Yaggi array on my house. There are several signals I receive, the closest is about twenty miles away. It locks on to the signals and stays, none of those little square pixel things that were so annoying. Because of the new found signal quality at home, I installed one on the coach to replace the over-the-air Winegard Batwing. It works on the same movable arm as the Batwing. If you can crawl around on top of your coach you can install it yourself, instructions and parts come with each antenna, including the power booster. A better picture for 50 bucks + shipping, and the at King Controls are pleasant to deal with.
