What is the purpose of installing a shark fin on a car?
1 Answers
Installing a shark fin on a car serves to enhance signal reception. When driving in mountainous areas, the car's signal can become very weak. With a shark fin installed, the signal reception inside the car is improved. The shark fin can also intercept radio waves, specifically the high-frequency waves from the car's radio, and it has the additional function of discharging static electricity, helping the car overcome resistance generated during driving. During car washes, it's important to avoid excessive cleaning of the shark fin. Although waterproof adhesive is used for the shark fin, over-cleaning can easily damage it and may lead to poor signal reception. For optimal radio performance, the antenna must be tightly integrated with the car's body metal, so it's essential to regularly inspect the shark fin's base and clean it periodically.
