A car antenna is a device used to receive radio signals, allowing the car to pick up AM, FM, or satellite radio stations. It is usually mounted on the vehicle's roof, side, or rear window. The antenna works by capturing electromagnetic waves from the air and converting them into sound signals that can be played through the car’s radio. Some antennas are fixed and extend outward, while others are retractable or integrated into the car's design to remain hidden when not in use.
