13.8.10 Completing the Installation
The installation should be completed by checking all mounting nuts bolts and screws,
securing all cables and weatherproofing the installation.
Warning: Finally tightening the antenna mountings may cause the antenna alignment to be
altered, due to distortion in the mounting bracket caused by action of tightening. It is
recommended that the installation tone be left turned on (armed) during this process so that
any movement can be noticed and counteracted by tightening the other side of the bracket.
13.8.11 Antenna Cable Fixing
Cables should be secured in place using cable ties, cleats or PVC tape. Care should be
taken to ensure that no undue strain is placed on the connectors on both the Connectorized
600 Series bridge and the Antennas and also to ensure that the cables do not flap in the
wind. Flapping cables are prone to damage and induce unwanted vibrations in the mast to
which the units are attached.
13.8.12 Antenna Connection Weatherproofing
Where a cable connects to an antenna or unit from above, a drip loop should be left to ensure
that water is not constantly channeled towards the connector.
