2.8 Align the Antenna
After the SU-A-EZ unit has been mounted, connected, and its radio is operating,
the antenna must be accurately aligned to ensure optimum performance on the
wireless link. This alignment process is particularly important for long-range
links.
To start the alignment process, you can just point the antenna in the general
direction of the Access Unit’s antenna using binoculars or a compass. For
accurate alignment, you must monitor the signal strength LEDs as the antenna
moves horizontally.
The signal strength LEDs indicate the downlink radio signal strength for the link.
The more LEDs that turn on, the stronger the signal.
When you move the antenna during alignment, the radio signal from the remote
antenna can be seen to have a strong central main lobe and smaller side lobes.
The object of the alignment process is to set the antenna so that it is receiving the
strongest signal from the central main lobe.
To align the antennas in the link, monitor the signal strength LEDs. For details
see
“LED Indicators” on page 15 . Perform the following procedure:
1 Pan the SU-A-EZ antenna horizontally back and forth while checking the
LEDs by rotating the pole-mounting bracket around the pole.
