accumulation on the ODU case if there are some problems with its connection to
the grounding contour.
Antenna pole, tower, ODU and lightning arrestor must be connected
to the first common grounding contour. Cable thickness must be not
less than 10AWG using corrosion-steady connectors. Grounding
contour development must be done by the skilled personnel.
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 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
Use GPS receiver and area map
