ABSTRACT:
An antenna cable drive and storage drum is driven by an electric motor to extend and retract a cable during a predetermined number of revolutions of the drum. A reaction switch, sensitive to drum rotation forces occurring at full extension or retraction, controls motor stoppage at the fully extended and retracted positions. A rotatable gear member supported on a stationary member is driven by a single tooth on the drum. In the event that the normal cable reaction load is not present, the drum continues to rotate beyond the full extension or retraction point such that an interference condition occurs between the gear member and the single tooth resulting in a high reaction load on the drum causing actuating of the reaction switch to discontinue operation of the motor.
