There is a small convex on the roof of many models，Because it looks like the fins of the shark，So everyone calls it "Shark fin”。This "shark fin" is actually the antenna of the car，Its role is very large，You can still keep your life at a critical moment。

"Shark fin" antenna has actually existed for a long time。Because it is not eye -catching，It is not valued during daily driving and car use，Therefore, the "shark fin" antenna is not recognized by consumers。In fact, the "shark fin" antenna has a very large role，Let's talk about the role of the "shark fin" antenna?

1. Enhanced car communication signal

Due to the high requirements of the car's sealing,，So the communication signal in the car is not very strong，This will make the car inconvenient during driving。To improve the communication signal of the car，The car is designed with antenna。These antennas have columnaries、Spiral -shaped。The design sense of these antennas is poor，seabet ioThe emergence of the "shark fin" antenna solves this problem。So is the role of the "shark fin" antenna?

The biggest advantage of the "shark fin" antenna is to enhance the communication signal。The signal receiving device of the "shark fin" antenna is built -in，Therefore, its ability to resist interference is strong，The interference of radio waves is also relatively small。Therefore, while raising the communication signal，It also enhanced the stability of the communication signal。

2. The role of the "shark fin" antenna plays a spoiler

The driving speed of the car is fast，Therefore, the requirements of air dynamics in the design of automobiles are very high。The design and development team of a car will analyze every detail of the appearance of the vehicle，Choose the best solution to reduce the air resistance coefficient。The design of the "shark fin" antenna is inspired by an aircraft maintenance technician in Australia.，Apply for a patent afterwards，and after being bought by BMW, the design has been transplanted to the car and used it to this day，This is why BMW car basically has the "shark fin" antenna。

Why does BMW spend a lot of money to buy this patent，The reason is when the "shark fin" antenna is driving at a high speed of the car，You can cut the air vortex on the roof。Especially at the speed of 100km/h or more，"Shark fin" antenna will help reduce the fuel consumption of the car。There are wind -cave experts doing experiments，"Shark fin" antenna will reduce high -speed fuel consumption when driving at high speed，This data is still very happy。

3. Release the car surface static electricity in autumn and winter

Enter the autumn and winter seabet loginseasons，Especially in the northern region，Cars often generate electricity when driving the door。"Shark fin" antenna can solve this problem well，"Shark fin"Built -in antennaA routine，You can pass the static electricity generated on the surface of the body。In this way, there will be no static electricity when opening the door and accelerate the heartbeat。

The "shark fin" antenna mentioned here is critical when life -saving refers to when driving in the wild，It is difficult to get rid of difficulties when encountering difficulties，Wild signal is not good，At this time, the strong communication signal of the "shark fin" antenna will play a role of "saving life"。The signal of the "Shark fin" antenna is enhanced and enhanced，VehicleGPS signalIt can make rescuers better positioning dangerous vehicles.At the same time, due to the application of the "shark fin" antenna，Enhance the signal strength of the car phone，Therefore, the possibility of calling for rescue is also very large。

The small "shark fin" antenna is very large，Not only enhances the communication signal、GPS signal，Can also release static electricity，It has greatly improved the fuel economy of high -speed vehicles，The most important thing is that the key time can protect your life。
