ABSTRACT:
A system is provided for automatically actuating an alarm whenever a would-be thief attempts to remove the antenna from a vehicle equipped with a C.B. radio or other communication system. The preferred embodiment includes a hidden switch which remains depressed by the antenna until it is partially unscrewed, at which time the switch closes the alarm circuit. For example, the horn of the vehicle may be connected to the switch and serve as the alarm.
