What is the function of the shark fin on a car?
1 Answers
The shark fin on a car mainly serves the following purposes: 1. Signal reception. In most cases, the shark fin on the car roof contains an electronic signal transmission device. The car's navigation system locates the vehicle through the equipment inside the shark fin. At the same time, it can also provide signals for devices such as the car's radio and Bluetooth, and can also enhance signal reception. 2. Static electricity discharge. The shark fin on the car roof can release static electricity from inside the car in dry environments, preventing many unnecessary troubles caused by static electricity. In addition to the shark fin on the car roof, static electricity can also be discharged by using a chain to transfer the static electricity from the rear of the car to the road surface. 3. Air spoiler. The shark fin on some performance cars can act as an air spoiler, making it more aerodynamic. It can press the car onto the road surface during high-speed driving, making the car more stable. 4. Decoration. Most cars use built-in antennas to receive signals, but they may also have a shark fin installed on the roof to make the car look better. It should be noted that if the car is equipped with an overly exaggerated decorative item, it needs to be registered with the vehicle management office; otherwise, it is an illegal act.
