ABSTRACT:
A plurality of plates are rigidly affixed normal to forward and rearward surfaces along a major axis of a maximal diameter of an asymmetrical rotating antenna. In the presence of a wind, any aerodynamic forces tending to produce aerodynamic rotational moments on the antenna are reduced by the interaction between the wind, which produces a boundary layer on the antenna, and the plates, which affect the boundary layer.
The net effects of the plates are to reduce the aerodynamic pressure difference between the forward and rearward surfaces of the antenna and to move the center of aerodynamic pressure closer to the center of rotation of the antenna. Due to these effects, the overall aerodynamic rotational movement on the antenna is reduced.
