I had the Winegard with wingman on my previous trailer and had no issues with it other than it occasionally not wanting to crank down or up (binding up) due to someone thinking they were being helpful by cranking it down when it was not perfectly aligned where it was supposed to be. That said, receptional was generally excellent.
My new 2 month old trailer came with a fixed dome antenna which I've identified as the Winegard RS-3000 after a trip on the roof.
In my driveway and my previous trailer, I could pull about 25 stations with about 5 of them being on the edge, sometimes digitizing and dropping/freezing picture for a few seconds. With the new trailer, I'm now pulling 40+ and 8 of them are from Dayton Ohio (I live on the eastside of Cincinnati) with antennaweb.org showing those towers as 43-44 miles away. The antenna is only rated for 35 miles but these are the results I'm seeing with it.
I thought I was given a piece of junk that I was likely going to have to replace but I'll admit when I am wrong. Impressed so far. I'll let you know if my opinion changes once I get a few more locations under by belt in the new camper next spring but between the driveway and my local state park which is 12 miles farther East of Cincy, it out performed my Winegard/Wingman Antenna that I had been singing the praises of for years.
