Abstract
A drive and storage drum is comprised of input and output frusto-conical sections. The input section has a resilient drive member and locking tangs disposed thereon which cooperate with slots disposed on the output section to provide a resilient drive connection and axial positioning between the input and output sections. An antenna cable is drivingly connected to the output section while a drive motor is drivingly connected through a worm drive to the input section. The resilient drive connection permits relative angular motion between the input and output sections when the end of cable travel is reached but the drive motor is not concurrently stopped.
