What is the use of "shark fin" on the roof of a car?

Nowadays, cars have become mass consumer goods. Many families have cars, some of which are more than 1, and cars have more and more functions. Many control keys have many functions that old drivers who have been driving for many years don't know. I wonder if the old drivers have noticed that some cars have long antennas at the rear, some have small triangles at the rear, and some have nothing at the rear.

The shark fin I'm going to talk about today is that small triangular object. Many people think it is used to decorate cars. After all, some cars don't have shark fin, so they are considered dispensable. Existence is reasonable. Although shark fin is small, it actually has many functions. What is the use of "shark fin" on the roof of a car? Many people don't know it yet, but they have gained knowledge!

The design of the "shark fin" antenna has actually been around for a long time. Because it is inconspicuous and not valued in daily driving and car use, the "shark fin" antenna is not recognized by consumers.

In fact, the "shark fin" antenna plays a very important role. First, it can intercept the emitted radio waves. The car antenna intercepts the high-frequency radio waves of the radio station and can receive the broadcast. Particularly useful. The radio we usually listen to while driving is its credit.

In addition to being used as an antenna, many people think that "shark fin" also has the function of conducting static electricity and disturbing current, which can release static electricity into the air during the driving of the car, thus protecting the safety of passengers in the car and the circuit of the car and playing an ideal disturbing current effect.

And with shark fin, wind resistance can be reduced. Little friends should know that driving will encounter air resistance. The faster the speed, the greater the resistance.

Although many cars will be equipped with special spoilers, fortunately, shark fin has a certain influence on air resistance, which can effectively reduce and overcome the influence of air resistance on cars, thus reducing the driving resistance of cars, enhancing the stability of cars and improving fuel economy, that is, saving fuel.

In addition, we can also install an LED light on the shark fin, which will keep flashing. When driving on the road, it can attract others' attention and remind the following driver to keep a distance from the vehicle to prevent rear-end collision.

In fact, there are shark fin antennas on the market now, and there are also shark fins purely for decoration. This kind of shark fin is very suitable for car owners who use hidden antennas in their cars, but they really hope that shark fin can enhance the sense of sports and fashion of their cars.
