[0002] Communication base stations, or public mobile communication base stations, are interface devices for mobile devices to access the Internet. They are also a form of radio stations, which refer to radio transceiver stations that transmit information to mobile phone terminals through mobile communication exchange centers in a certain radio coverage area. Lightning damage to mobile communication base station equipment and the resulting communication interruption not only cause huge economic losses, but also seriously affect the safe operation of the communication network. The antenna feed line of the mobile communication base station is connected between the antenna and the transceiver in the machine room, so the antenna feed line is an important channel for introducing lightning into the machine room.

[0003] Lightning rods used for lightning protection are generally installed on top of communication base stations that need protection. They use their protruding parts that are higher than the protected objects to draw lightning toward themselves, and then conduct the current to the ground through wires. Therefore, lightning rods are easily damaged. Current lightning rods are fixed by welding, which makes their removal or replacement more cumbersome. Summary of the invention
