Abstract: This invention describes a method, an apparatus, and a system for optimizing antenna performance by remotely adjusting the plumb-to-level (absolute measurements with respect to true vertical) and the compass heading (absolute compass heading direction with respect to magnetic North) of one or a plurality of communication antennas by electromechanical means.
