Replaceable motor operated antenna

摘要

A motor operated antenna for an automobile. The antenna includes a number of telescoping collapsible sections which form a removable unit. A reversible electric motor is mounted next to a fixed antenna tube in which the unit is positioned. The motor raises and lowers the sections in response to a switch actuated by a user. In the event any of the sections comprising the unit are bent or broken a collar holding the unit in place in the tube is loosened and removed. The unit can be withdrawn from the tube and replaced with a new unit.
