ABSTRACT:
An antenna steering mount includes two basic building blocks which are joined together to form any of the known steering-axis combinations. Each block includes a cylinder cut at an angle to form a cylindrical wedge. The wedges are joined together by bearings at their interface, and motors are used to counter rotate the two wedges relative to each other. One end of the complete assembly is attached to a mounting platform, and the other end includes mounting features for attaching an antenna dish thereto. Various two- and three-axis steering configurations are disclosed including combinations of azimuth, elevation, cross-elevation, and cross-level steering.
