The Winegard dish is either Dish (Model SK-1000) or Direct TV (Model SK-3005 and was superseded by SK-SW3). Usually, the Dish reflector was black and the DTV reflector was grey. If you find you have the Dish unit and want to watch DTV, you have to replace the entire unit. They used to make a conversion kit, but I think they discontinued it.
