Abstract
The driving apparatus for a power antenna, e.g. an extensible-retractable automotive radio antenna, is provided with stability function which controls the operation of the motor driving the power antenna until the power antenna is varied into a state for performing normal operation, and provides hysteresis to prevent a state of the controlling signal from being varied too often by a voltage drop generated in rotation of the motor.
