Step 13: Complete the installation as detailed below.
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 : Final tightening of the antenna mountings may cause the antenna alignment to
be altered due to distortion in the mounting bracket caused by tightening. It is recommended
that the installation tone be left turned on (armed) during this process so that any movement
can be noticed and counter acted 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 version
of the PTP 400 Series Bridge unit 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.
