13.7.7 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.
Recommendation: 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 Section 7.7.11 "Aligning the PTP 600
Series Bridge ODUs".

13.7.9 Aligning Separate Antennas

When using separate antennas to achieve spatial diversity, one should be mounted with
Horizontal polarization and the other with Vertical polarization.
The following steps should be followed:
Step 1: Mount the Antennas
Step 2: Mount the connectorized version of the PTP 600 Series Bridge unit
Step 3: Route and make off the ends of the Antenna cables
Step 4: Connect the antenna cables at the antennas
Step 5: Connect one of the antenna cables at the Connectorized version of the 600 Series
bridge unit.
Step 6: Connect the Connectorized 600 Series Bridge ODU to PIDU Plus cable and
configure the unit as described in Section 7.7 "Connecting Up".
Step 7: Align the connected antenna using the tones as described in Section 7.7.11 "Aligning
the PTP 600 Series Bridge ODUs".
Step 8: Connect the other antenna to the Connectorized 600 Series bridge.
Step 9: Disconnect the cable to the already aligned antenna.
