Take a minute to understand the shark fin on the car body
To receive signals, the "shark fin" has a signal receiving device on the 'interior, which has strong anti-interference ability and little radio wave interference. While improving the communication signal, it also improves the stability of the communication signal. In addition to the basic function of the final signal, the shark fin is also responsible for receiving communications, GSM network signals, positioning GPS signals, miscellaneous. multimedia functional services and vehicle positioning, including navigation.
Release static electricity. In addition to receiving signals, shark fins also have the function of releasing static electricity which accumulates in the "shark fins" through conductive wires and is then released into space, eliminating the 'electricstatic ity. static electricity generated by the car and spoil traffic. According to the principles of physics, the car will encounter resistance when driving. The faster the speed, the greater the resistance. If there are no shark fins, a small vortex-like airflow will form. formed above the car, resulting in increased wind resistance and noise, with the existence of shark fins, the airflow will be divided, thereby reducing wind resistance, which can effectively reduce fuel consumption and noise.
To avoid rear-end collisions, some “shark fins” are equipped with LED lights, and some even use the principle of solar energy. They will flash alternately at night, which can remind the attention of vehicles behind, in particular. in extreme weather. It has a good effect.
