I installed my Wingman last Memorial Day Weekend. That Friday I tried my new HGTV without the added Wingman add-on and received maybe 30 channels. Saturday I installed the Wingman and receive about 40 channels. If you have the Winegaurd bat-wing antenna it is a simple 2 minute install. We'll worth it......Sure like the flat panel TV's sharpness and the small amount of space it now takes up. We used to place the old box 13" TV on the floor when traveling. Now we place the 22" flat panel in a blanket behind the couch when traveling.
Here is a link to a thead that shows pictures of the batwing before and after
installing the Wingman.
