There is an accessory called the "wind deflector kit" shown on the Winegard site with a model number of BW-1000. Here is the link:

I have tried to get Camping World and other sources that carry Winegard to price/order this part but was unsuccessful. I am sure one could make this little metal part in your own garage, but here is what worked as an alternative...
What I did instead for my coach was to place two self adhesive soft vinyl bumpers under the front edge of the antenna wing when in the stowed position. These were adhered to the roof surface, so they do not interfere with the raised antenna but do help reduce the 'tapping' noise of the antenna touching the roof when vibrating in the wind while under way. For my coach, the noise started at about 50 MPH so it was really annoying during any highway driving...
Hope this helps!
