Anything is better than nothing. I've used the Winegard version at times. Also have the 4-element Winegard yagi.
When I was in the Navy, back in Southern Maryland, in the days before the current proliferation of stations (we're talkin' 1976-77), I had a ten element FM yagi and a rotor on a fifteen foot mast (all were Radio Shack in-stock/in-store back then). Got over one hundred FM stations, depending on whether I aimed at DC, the Eastern Shore, Norfolk, or west. Probably would get 500 stations now days.
