4.1 Unpacking
Open all boxes supplied and check the contents with the enclosed packing list.
Inspect units and parts for possible transport damage.
4.2 Preparation
The antenna is supplied in a cardboard box and is bolted to a pallet. Cut the
straps around the sides, remove the lid and take the sides off by lifting over
the radome. The antenna system can be removed from the pallet by removing
the 4 M10 screws from underneath.
4.3 Grounding
It is recommended that the antenna is grounded via its mounting bosses to its
mounting plate as the RF coax screen and antenna electronics ground are
referenced to this point.
The metal underneath the head of at least one bolt must be clean of insulating
protective coating and a serrated washer should be used. After the bolts are
tightened, it is recommended that the area is suitably sealed in order to avoid
corrosion of the grounding point.
It is recommended that all 4 bolts are used for grounding. Use stainless steel
bolts and washers.
For further grounding information read Appendix G Grounding and RF
protection on page 105.
