What exactly is the little tail on the roof of a car for?

What is the use of a "small tail" on the roof of a car? Why do some cars have some and some don't?

Some of our attentive friends will find that some cars will have a "little tail" on the top, what is it for?

Some people will say: this is the antenna! That's true, but what is this antenna for?

Why do some cars have and some don't? And why does this antenna look different? Do you think that this little thing also seems to have a great origin?

First of all, why do some cars have them and some cars don't?

Actually, this is a different car process, and there are so many kinds of car antennas:

The first is that old-fashioned cars use that kind of retractable antenna.

It's the kind of antenna that the radio we used to listen to can be stretched and shortened; But now it's almost impossible to find this antenna in cars.

The second is the whip antenna, which is not retractable, and is now used more in cars.

The appearance is relatively good-looking, and now it is more fashionable to dress like this. But there is also a small disadvantage that the wind noise is relatively large. Think of a small stick on the roof of the car, and when the wind blows, there will be a whining sound.

How loud is the sound, we think about when we were children when we picked up a stick, we can hear a very obvious sound.

The third type is the automotive glass antenna.

This antenna is embedded in the front windshield or rear windshield, so we can't see the small tail behind the car when the glass antenna is generally installed.

The fourth type is the shark fin antenna.

It is a popular form of antenna at present, why? Many of our friends will also modify their antennas into shark fins, and some even install them directly as decorations.

What is the antenna used for?

Generally speaking, we know that it is the antenna of the radio, but if we want to make such a large device on the body for the sake of the radio, it seems a bit too much. So the car manufacturer tried to let him integrate several other functions.

He is also an electrostatic discharger, when the weather is dry, the car is prone to static electricity, if you do not release static electricity, it will damage the circuit in the car, the antenna can release the static electricity accumulated in the car shell, protect the safety of passengers as well as the body circuit. Before the antenna was used to release static electricity, it was discharged by installing a mopping strip chain at the exhaust pipe.

The antenna also has the effect of turbulence, which uses the principle of aerodynamics to achieve our ideal turbulence effect in the rapid movement of the car. Some high-end cars also have the effect of enhancing signal strength if there is an on-board **. Enhanced car navigation, GPS, GPS, and more.

The role of the small antenna is still very large!

Why do cars have small tails on the top, and what is the use of it.

You can always see it everywhere on the street, like many cars nowadays will have a small tail on the roof, so do you know what this little thing does? Speaking of which, some friends may say, isn't this an antenna, yes, this is an antenna, but do you know that antennas also have different functions, just like the antenna above the roof of a police car, the antenna above a luxury car, the antenna above a BMW car, don't underestimate this small antenna, it has a university question. Some cars have antennas that have the aerodynamic effect of air spoiler!

Many experts will know that although this little tail is small, it can save people from fire and water at important moments, and the name of this small tail is "shark fin". It is carefully crafted by professional designers, this little tail is not only an ornament but also an important little thing, its function is very powerful! You may find that its design is a bit like the dorsal fin of a shark, yes, the design of this small tail is inspired by it, the function of the dorsal fin of the fish is to reduce the resistance of the water to them, so the design of this small tail is naturally combined with this to reduce the resistance of the air to the car.

Everyone knows that the highway speed is very fast, with this small tail can reduce the resistance of the wind to the car, so as to stabilize the body, so that there is another layer of protection in driving safety.

This little tail also has another function, and that is a lightning rod. Autumn and winter are the most likely seasons to generate static electricity, so if these can not be released, it may cause accidents, at this time the small tail appears, this small thing can introduce static electricity to the micro end of the antenna to release, then driving safety is guaranteed. This small tail can also be divided into two functions, one is connected with the internal line to become a functional antenna, and the other is to release static electricity to further enhance the signal, which is called a decorative antenna.

Which one do you prefer? No matter which one is a good choice for consumers, thunderstorms can also be converted into lightning rods, so that driving and driving safety. So don't underestimate the little things, as the old saying goes, although the sparrow is small, it has all the organs!

For the sake of good looks, let's just say that the head on top of an airplane is like an airplane.

It can enhance the signal in the carNowadays, the society is already an Internet society, and there is almost nothing that can be separated from the Internet.

I believe that all friends have experienced the feeling of being electrocuted when opening and closing the door, this is because the body of the car is very easy to generate static electricity, and the car with a small tail design can absorb the static electricity of the body and release it directly, so that the friends will not be electrocuted when opening and closing the door.

Almost every car will have a small tail, so a small tail is essential when it is manufactured, and each car may have a different shape.

This styling design can be very effective in reducing the wind resistance of the vehicle at high speeds, improving fuel economy.

Many people may think that the small tail design on the top of the car is just an ornament, but in fact it is not as simple as an ornament, its role is very large.

It can make the navigation system on the car more agile, and if the signal in the car is not good, then the owner will not be able to use the navigation system.

Effectively reducing the resistance of the wind, we all know that the small tail on the top of the car is a streamlined shape, also known as a shark fin.

Depending on the price of the vehicle, the function of the small tail will also be different, but generally speaking, it is divided into three functions.

Why do cars have small tails on the top, and what is the use of it.
