13.7.4 Miscellaneous supplies

The following miscellaneous supplies will be required:
Cable ties, cable cleats – for securing cables
Self-amalgamating tape – to weatherproof the RF connectors
PVC tape – for additional protection of the RF connectors and securing cables

13.7.5 Mounting the Connectorized 300 Series Bridge

A Connectorized PTP 300 Series bridge is shipped with the same bracket as supplied with an
Integrated unit. Details on the use of this bracket can be found in
Series Bridge should be mounted in a position that gives it maximum protection from the elements,
but still allows easy access for making off the various connections and applying the recommended
weatherproofing.
When using dual polar antennas the Connectorized PTP 300 Series bridge should be mounted in
such a position as to minimize the cable length, keeping losses to a minimum (taking into account
the minimum cable lengths required by the FCC regulations, see
USA / Canada – 5.8 GHz" .
When using separate antennas the Connectorized PTP 300 Series Bridge should be mounted in such
a position as to minimize both cable runs between the unit and the antennas. It is not necessary
to mount the Connectorized PTP 300 Series Bridge at the mid point between the antennas.

13.7.6 Mounting the antennas

The Antennas should be mounted according to the manufacturer's instructions. Actual antenna
position will depend on the available mounting positions and link requirements. It may be necessary
to mount the antennas 20m apart or at a certain distance from the ground to get the desired results.

13.7.7 Alignment Process

When aligning antennas deployed with a Connectorized PTP 300 Series bridge unit it may not be
possible to hear the alignment tone emanating from the unit. In this case it may be necessary for
a second installer to assist in the operation. Alternatively, it may be possible to extend the tube
on the supplied stethoscope to give a longer reach.
Tip: Fine antenna alignment can sometimes be achieved by tightening and loosening the bolts on
either side of the antenna mounting bracket, rather than trying to turn the whole bracket on the
mounting pole.

13.7.8 Aligning Dual Polar Antennas

The process for aligning a dual polar antenna is the same as aligning an Integrated unit with an
integrated antenna. This procedure is detailed in
Bridge ODUs".
