Abstract
A concentric pulley drive assembly is disclosed as having a central pulley mounted to a motor axle and rotatably driven therewith by a drive motor. A partial pulley in the form of a partial annulus is positioned about a portion of the periphery of the central pulley concentrically with respect to the motor axle. A tape strip coupling the two pulleys transmits torque from the central pulley to the partial pulley to induce annular rotations of the partial pulley about the motor axle commensurate with the annular rotation of the central pulley. An antenna or sensor support platform is coupled to the extremities of the partial pulley for pivotal positioning about the motor axle in conjunction with the annular rotation of the motor axle.
