This shark fin was first introduced by BMW. It is an antenna. Only BMW can make this antenna into the shape of a shark fin, which can reduce air resistance. Some cars without shark fins also have antennas, and some cars have no antennas on their roofs. The antenna on the roof has many functions, such as improving cell phone signals, receiving radio signals, receiving gps signals and so on. Don't unscrew the antenna on the roof casually, which will affect some functions and cell phone signals in the car. BMW's shark fin plays a necessary aerodynamic role, and BMW has applied for a patent on this day.
The function of shark fin is to replace and surpass the original rod antenna, with unique shape and harmonious collocation. A small shark fin can make the car more fashionable and dynamic. The functional shark fin antenna needs to be connected to the internal circuit of the car, which can integrate various powerful automotive electronic functions such as FM, GPS and GSM. The decorative shark fin antenna can release static electricity and enhance the signal.
Traditional car antennas include tie-rod antenna, _ antenna and car glass antenna. If there is no shark fin antenna in the car, it is likely that a traditional antenna is installed, and the shark fin can be modified by itself. Another kind of antenna is a built-in antenna, which is invisible, but it improves the aesthetic effect and plays a certain role in passing. (Photo/Text/Photo: Pacific Auto Network Chen Miaoling)
