ABSTRACT:
Apparatus for an earth station antenna is disclosed herein including a parabolic dish antenna pivotally carried on an upper support post mounted for rotation about a vertical axis. Pivotal linkage interconnects the antenna with the upper support post for rotation about a horizontal axis. Power drive is carried in the upper support post for pivoting the antenna about its horizontal axis via the linkage while separate power drive operably couples between the upper support post and a stationary lower post for rotating the upper support post and the antenna about the vertical axis. The lower end of the lower support post is provided with a mounting recess for insertably receiving the terminating end of an upright mounting stanchion.
