I also have the 2021 3300DL. We replaced the Winegard Air 360+ with a DISH Playmaker dual mounted on roof. We learned that you cannot use a splitter anywhere between this sat and Dish receiver. We traced a coax from sat to the bedroom TV but cannot locate the coax to the living area TV. We have not checked behind wet bay or behind basement coax. Any ideas where else to look besides in the TV cabinet, fire place area?
