13.8.5 Mounting the Connectorized 600 Series Bridge

A Connectorized 600 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 section 3.3.7. The 600
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 600 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 section 13.7).
When using separate antennas the Connectorized 600 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 600 Series bridge at the mid point between the
antennas.

13.8.6 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.

13.8.7 Alignment Process

When aligning antennas deployed with a Connectorized 600 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.

13.8.8 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 section 7.7.11.
