3.4 Against Lightening and Grounding
Protection
CAUTION:
This is unlikely to happen, but since LTE base stations are very complex
devices, we recommend that you test them on the ground to make sure
everything is okay before installing them on the tower.
In order to protect GPS, external antenna and RJ-45 port, external lightning
protection devices must be prepared.
Grounding Notes:
 The ground wire adopts yellow-green wire that is no smaller than 16 mm².
 Grounding principle: as near as possible.
 The base station is connected to a reliable outdoor grounding point (grounding)
through two grounding screws.
 The connection between the grounding point and the grounding rod must be
reliable and reliable. The terminals need to be rust treated. This can be done by
antirust paint, antioxidant paint, grease and so on.
