Power operated radio antenna is a telescoping type antenna, extended and retracted by a reversible electric motor.
Automatic power antenna is controlled by a combination of an internal relay and limit switches which are built into antenna motor housing. Antenna is actuated when radio is switched ON and ignition switch is in ON or ACCESSORY position. When ignition or radio is turned OFF, antenna mast should retract fully.
Many antenna problems may be avoided by frequent cleaning of antenna mast telescoping sections. Clean antenna mast sections with clean soft cloth.
Power antenna system is used on premium systems only. Battery feed for antenna is provided from M1 circuit on radio and junction block, and X60 circuit on power amplifier. X60 circuit is HOT when radio is ON. Antenna ground is a case ground.
