4.5 Lightening Protection Cautions
Lighting protection include direct lighting protection and indirect lighting protection. We
should avoid fix the device to face the direct lighting protection. Below we just list some
essential and useful methods to protect from indirect lighting, induction lighting or surge.
1.The lightning rod should be fixed above the tower with device or gateway. And the
gateway should be in the protection area of the lightning rod.
2.When the gateway is fixed to the building, the gateway should be in the protection area of
the lightning rod which is on the top of the building. If there is no lightning rod on the top of
the building, please make sure that the gateway would not be in the influence area of the
lightning, or you must fix a lightning rod above the antenna and connect to the ground of
the building or lightning protection network.
3.The small lightning rod should be made of circular steel tube with diameter more than
16mm. The lightning rod should be higher than the top of the antenna 1m or more.
4.Lightning rod ground down lead should be no less than 8 mm diameter galvanized round
steel or cross-sectional area not less than 48 mm squared multi-strand copper wire. When
using multiple strands of copper wire for grounding, please make steel tube to prevent the
mechanical damage.
5.When the gateway is put nearby the lightning protection area, please make sure all the
device include antenna put below the lighting protection area.
6.Don’t put or fix the cable to the lightning protection line or area.
7.Please ground the fixture of the gateway.
