The function of shark fin antenna: shark fin antenna was not recognized and respected by the public at first. A few years ago, most of the antennas we saw in cars were rod antennas. In order to enhance the communication signal of automobiles, BMW has specially developed shark fin antennas for BMW series vehicles. Since then, shark fin antennas have been widely loved by riders because of their generous appearance, complete functions, diverse colors, integration with the whole body, fashion, dynamic and dazzling appearance, and various shark fin antennas for middle and high-end vehicles have been launched in the market. Shark fin antenna overcomes the shortcomings of traditional rod antenna, whip antenna and automobile glass antenna, and integrates all the functions of ordinary antenna with the latest modern electronic technology. It has the functions of releasing static electricity, amplifying communication signals, interfering current, improving the accuracy of GPS system, and also has the functions of radio FM antenna, GSM communication antenna and GPS antenna. The aerodynamic principle is applied to effectively eliminate the airflow noise of the traditional rod antenna, and the driving is quieter.
When the weather is dry, cars are prone to generate static electricity. Earlier, a mop chain was installed at the exhaust pipe to release static electricity. With the shark fin antenna, this problem has been solved efficiently. Shark fin antenna makes full use of the characteristics of electrons walking at the tip, introducing electrostatic electrons into the tail tip of shark fin antenna and releasing them. No matter where the shark fin antenna is installed in the car, it can reduce the static electricity on the car surface.
