Well, I have to laugh at myself because it took only 4 years for me to examine what may be wrong with it. It really didn't affect reception because the picture was always clear.....when I could get a channel. I live 40 miles east of Knoxville and I am pulling in the K'ville local stations now. Even have Asheville PBS station. I found no identifying placard on the antenna so I will guess its a sensar II or III, no wing man on it. I am quite thrilled with it now because I do use it for a man cave when its parked here and keep the 'fridge stocked and some goodies on hand. Now I gots TV too with some better choices. Thanks again you guys.
