Has any one tried the winegard wingman that just attaches to the existing antenna that is advertised in Camping World catalog. Since I still have the old TV and use the converter Box I was thinking about trying the add on for a better signal but I am afraid I will just be wasteing my money, haven't seen a post any where where some one has actually used one. They also have a replacement head that suppose to help too. My 5th. wheel is a 2000 Sunnybrook which has the older type antenna. It does pretty good on antenna I have but I pick up fewer stations.
