Abstract: A pole-mounted directional microwave antenna secured to a platform is disclosed. The platform is rotatably mounted atop the pole so that the elevation angle of the beam axis of the antenna may be controlled. A stabilizing outrigger rod is mounted parallel to the pole, and the rod is linked to the platform. Spacers between the pole and the rod maintain a fixed separation, and when the pole is deflected in a plane containing the beam axis the rod is deflected in a parallel manner causing the platform to rotate so that the beam axis remains parallel to its undeflected orientation, thus automatically compensating for wind-induced pole sway in the direction of propagation. Three rods are used to compensate for sway in any direction.
