Technical Field
[0001] This utility model relates to the field of vehicle-mounted antenna technology, and more specifically, to an integrated vehicle-mounted antenna with electromagnetic pulse protection. Background Technology
[0002] A vehicle-mounted antenna is a device that intercepts high-frequency radio waves emitted by a transmitter and transmits them to a receiver in a vehicle radio, car phone, or radio navigation system for carrier demodulation. It is a key component in a vehicle that plays a role in signal transmission and reception.
[0003] Vehicle-mounted antennas typically employ series-connected, separate surge protectors, primarily for protection against the effects of induced lightning strikes. Currently, when adding surge protectors to vehicle-mounted antennas, they are usually installed below the antenna base, inside the interior roof trim. This makes them difficult to repair or replace after a lightning strike or other electromagnetic pulse, and the assembly process requires professional guidance to ensure the reliability of the radio frequency connection. Therefore, this invention provides an integrated electromagnetic pulse protection vehicle-mounted antenna. Summary of the Invention
