Aligning The Antennas - Cisco Aironet 1400 Series Manual

To verify the alignment and make finer adjustments, you can connect a
voltmeter to the bridge's RSSI voltage port. The port provides a DC voltage
proportional to the received RF signal level. Panning and tilting the antenna
through the signal path produces varying voltage readings. The maximum
voltmeter reading (peak) indicates the optimum antenna position.

Aligning the Antennas

The antenna alignment process for the integrated antenna model is described
below in simplified terms. Optional antenna model procedures are similar.
Note
Polarization for the antennas you are aligning must be the same.
Begin at the root bridge location and perform the following steps:
1. Position the bridge's antenna to the azimuth, elevation, and polarization
recommended by the site survey.
2. Power up the bridge and confirm that it is a root bridge and is in
installation mode. (Wait until the Install LED changes from blinking
amber to blinking green.)
3. Proceed to the non-root bridge location.
