Grounding
Antenna should be placed on the mast on the level that is at least 1 meter lower than a mast’s
top. In this case it is of big probability that the lightning strikes the mast and not the antenna.
The mast is to be grounded on the grounding contour according to your local standards.
A special attention should be paid if antenna used is not DC-shorted. In this case additional
lightning arrestor should be used between the antenna and ODU. Suggested grounding
diagram is shown on the picture below.
Antenna pole, tower, ODU and lightning arrestor should be connected to the first common
grounding contour. Cable thickness should be no less than 10AWG using corrosion-steady
connectors. It is highly recommended to entrust grounding contour development to the skilled
personnel. IDU should be grounded to the same contour as customer LAN, having the second
common grounding contour.
