Abstract
In a motorized automobile antenna control device for an antenna system wherein an antenna is raised when power supply of a radio receiver is switched on and lowered when the power supply is switched off, the antenna is prevented from being lowered for a predetermined period of time, for example two to ten seconds, after the power supply of the radio receiver is turned off by a timer so that unnecessary raising and lowering motions of the antenna are prevented when an ignition switch of an automobile is turned on.
