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.
2.3.8 Antenna Alignment
To obtain maximal system performance antennas must be precisely aligned one
towards another according to LOS requirements. General recommendations for
antenna alignment are the following:
 Align antennas using optical equipment (binoculars, spyglass) accompanied
by mobile phone actions coordination
CAUTION
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.
