Abstract: A wind deflection device includes a vertically-oriented elongated body having diverging side walls. In one embodiment of the invention, a plurality of brackets are mounted between the diverging side walls and have apertures which will snap onto and grip a vertically-oriented vehicle aerial. In a second embodiment of the invention, a continuous longitudinal bracket of a rubber-like material is utilized, which has a longitudinal slot will snap onto and grip the vehicle aerial. The brackets in both embodiments of the invention are designed to grip that portion of a pennant which is wrapped around the vehicle aerial. A third emodiment of the invention utilizes a bust-like configuration mounted on the forward side of the wind deflector, which is designed to represent a mascot of a collegiant or professional sports team.
