What's the use of the small antenna on the top of a car?
The first is that old-fashioned cars would use that kind of retractable antenna, which is the kind of antenna that we can listen to before the radio can be extended and shortened; but now it is almost impossible for cars to find such an antenna. The second type is a whip antenna, which cannot be retracted. Now it is used in cars. The appearance is more beautiful, and it is more popular now. However, there is also a small drawback that wind noise is relatively large. Think of a small stick on the top of the car. After the wind blows, there will be a buzzing noise. How loud is the sound, and when we think about sticking sticks when we were young, we can hear a very clear sound. The third type is an automotive glass antenna. It is this antenna that is embedded in the front windscreen or the rear windshield. So, in general, a car with a glass antenna, we cannot see the small tail behind the car. The fourth is the shark fin antenna. It is an antenna type that is currently more popular. Why is it? Pretty Well~ Many of our friends will also modify their antennas into shark fins, and some even directly install them as decorations.
