Antenna feeder lightning protection device (also known as surge protection device SPD) adopts coaxial in-line design, instantaneous response to lightning surge, and is suitable for lightning protection of various RF signal transceiver system. The antenna feeder lightning arrester is connected in series to the antenna feeder line and can be installed on the LPZ0B to LPZ2 interfaces of the lightning protection zone to prevent the damage to the antenna and transceiver equipment caused by the overvoltage induced by the feeder. The antenna feeder lightning protection device has the characteristics of wide frequency band, small standing wave ratio, low insertion loss and high transmission rate. It is widely used in communication base stations, radar stations and other fields.
