The purpose of installing a shark fin on the car roof is: 1. It can release static electricity from the car body; car static electricity is very common, especially in dry seasons like winter, when excessive static electricity can easily occur; 2. It can intercept and transmit radio waves. In addition to intercepting these radio waves, the shark fin antenna can also transmit them to various devices inside the car that require different types of radio waves. The shark fin car antenna product utilizes internationally leading electronic technology. Compared to traditional telescopic antennas, whip antennas, and car glass antennas, the shark fin car antenna integrates powerful automotive electronic functions such as FM, GPS, and GSM.
