Abstract
An antenna cable drive and storage drum has a member threaded on the housing and rotatable with the drum. The member is effective to release a pair of stop plungers which engage between the drum and housing to create a substantial resistance to further rotation of the drum if the drum is rotated in either direction more than the predetermined number of revolutions which are needed to either fully extend or fully retract the cable.
