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 Section 7.7.11 "Aligning the PTP 500
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 500 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 500 Series
bridge unit.
Step 6: Connect the Connectorized 500 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 500 Series Bridge ODUs".
Step 8: Connect the other antenna to the Connectorized 500 Series bridge.
Step 9: Disconnect the cable to the already aligned antenna.
Step 10: Align the second antenna using the tones as described in Section 7.7.11 "Aligning
the PTP 500 Series Bridge ODUs".
Step 11: Re-connect the second antenna to the Connectorized 500 Series bridge (Note: you
will notice the tone pitch increase as you re-connect the second antenna due to the additional
received signal).
Step 12: Use the relevant status web pages to check that you are getting the results you
expect from your link planning.
