Abstract
Abstract A mount for an earth station antenna includes an hour angle beam suppoting the antenna for pivotal movement of the antenna about an hour angle axis determined by the position of the hour angle beam. An adjustable azimuth strut is connected to the antenna for pivoting the antenna about the hour angle axis. Two pairs of struts pivotally support the hour angle beam at spaced pivot points to permit adjustment of the hour angle axis so that the antenna can be pointed at a satellite. The lower ends of the two pairs of struts are pivotally connected to a foundation on horizontally spaced axes with the lower ends of the pair of struts connected to the lower pivot point on the hour angle beam being spaced farther away from the lower end of the beam than the lower ends of the other pair of struts, so that pivotal movement of the hour angle beam pivots the upper and lower ends of the beam along different arcs. An adjustable elevation strut pivots the two pairs of main support struts about their pivotal connections to the foundation to adjust the vertical positions of the upper ends of the struts to effect pivotal movement of the hour angle beam.
