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.

13.8.9 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.

Step 7:

Align the connected antenna using the tones as described in section 7.7.11.

Step 8:

Connect the other antenna to the Connectorized 600 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.

Step 11:

Re-connect the second antenna to the Connectorized 600 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.

Step 13:

Complete the installation as detailed below.
