Through wire and equipment to understand whether it can play lightning protection effect, is it possible to become a lightning needle?
If the needle can only be placed on the rod, it is recommended that the antenna feeder be installed directly inside the boom and take necessary insulation reinforcement measures.If possible, install surge protectors at the antenna and indoor receiving equipment.
If the pole holding height is relatively high, the method of installing the lightning rod at the top of the rod can also be considered, but be careful. At this point, it is necessary to consider the possibility of flashover and breakdown of the antenna and feeder after the lightning rod is struck by lightning, and the electromagnetic induction of the electromagnetic field when the lightning flows into the ground.
The distance from the ground to the ground is preferably greater than 0.6m, and away from the pedestrian road and the entrance, otherwise it is very dangerous.Holding pole only 1 meters high, it is suggested that alone next to the antenna to do lightning protection, and 2 meters away from the antenna installation, height requires a simple calculation.
