10.7.6 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.
NOTE
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.

10.7.7 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 6.6.1 "Aligning the PTP 300
Series Bridge ODUs".

10.7.8 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:
1. Mount the Antennas
2. Mount the connectorized version of the PTP 300 Series Bridge unit
3. Route and make off the ends of the Antenna cables
4. Connect the antenna cables at the antennas
5. Connect one of the antenna cables at the Connectorized version of the PTP 300
Series bridge unit.
6. Connect the Connectorized PTP 300 Series Bridge ODU to PIDU Plus cable and
configure the unit as described in Section 6.5 "Connecting Up".
7. Align the connected antenna using the tones as described in Section 6.6.1 "Aligning
the PTP 300 Series Bridge ODUs".
