If you have a Winegard Sensar, then the Wingman should fit if you have about 10" of clearance on the non-post side of your antennae....in the folded down position. Some members of the forum have run into clearance problems in the down position, whether it be their AC or a fridge or roof vent.
I have the Wingman, and can see an improvement. It has brought in another station or 2, and the weaker stations don't "freeze" up as bad now.
