Where is the standard position for a shark fin antenna?

The shark fin antenna is installed on the roof of the car, above the rear windshield. Utilizing electronic properties, the shark fin antenna directs static electricity to its tip for release. Regardless of its installation position on the car, it effectively reduces static electricity. The specific functions of the shark fin antenna are as follows: After installing a shark fin antenna, airflow is split by the fin before forming tail vortices, thereby reducing driving resistance. Particularly at speeds above 100km/h, the "shark fin" antenna significantly aids in lowering fuel consumption. Wind tunnel experiments have shown that the "shark fin" antenna can reduce high-speed fuel consumption by 3%, a remarkably encouraging figure. Essentially, the shark fin serves as a car antenna, intercepting high-frequency radio waves from transmission towers and delivering them to the car's radio, mobile phone, or navigation receiver for demodulation. Given cars' high sealing requirements, internal communication signals can weaken. To enhance signal strength, antennas are designed into vehicles. The "shark fin" antenna's primary advantage over traditional antennas is its superior signal enhancement. Its built-in signal receiver offers strong anti-interference capabilities and minimal radio wave disruption, ensuring both improved signal strength and stability. Additionally, it eliminates the aerodynamic noise associated with rod antennas, providing a quieter ride. Moreover, during dry seasons, vehicles are prone to static electricity, which can damage onboard circuits. The "shark fin" antenna effectively addresses this issue by acting as a static discharger, safely releasing accumulated static to protect both vehicle electronics and passenger safety.
