1 Answers
Here are the functions of the shark fin on the roof of a car: 1. Signal reception: Generally, the shark fin on the roof of a car contains an electronic signal transmission device. The car's navigation system uses the equipment inside the shark fin for positioning. At the same time, it can also provide signals for devices such as the car's radio and Bluetooth, and can enhance signal strength. 2. Static electricity discharge: The shark fin on the roof of a car can discharge static electricity inside the car in dry environments, avoiding many unnecessary problems caused by static electricity. In addition to the shark fin on the roof, static electricity can also be discharged from the car to the road surface using a chain attached to the rear of the car. 3. Airflow disruption: The shark fin on the roof of some performance cars can disrupt airflow, making it more aerodynamic. This helps press the car onto the road surface during high-speed driving, improving stability.
