What is the function of the antenna on the roof of a car?
1 Answers
Car roof antennas serve the following purposes: 1. The antenna on a car roof, also known as a car antenna, is primarily used to receive external signals, allowing you to listen to the radio inside the car. 2. On police cars, the antenna functions to receive mobile radio transmissions, especially special band information from the police. 3. In addition to receiving signals, the car antenna also acts as a static discharger, releasing static electricity accumulated on the car's body to protect passengers and the vehicle's circuitry. 4. On some high-end vehicles, the antenna has an aerodynamic function to reduce air turbulence. Some can even serve as antennas for car phones, significantly enhancing signal strength.
