Apparatus for automatically erecting a vehicle mounted antenna of the type utilized for citizens band radios. A p.m. motor provides drive to pivotally move the antenna and a logic circuit comprising only a double-pole-double-throw and two secondary switches provides fully automatic performance in conjunction with turning on the radio. LEDs are selectively illuminated to show antenna status by utilizing a circuit logic path incorporating the winding of the motor. A friction coupling override arrangement protects the erecting mechanism while retaining drive logic.
