Installing and Connecting an Access Point

   

3.

Pan the antenna horizontally back and forth while checking the RSSI voltage. If 
using the pole-mounting bracket with the WLA620, you must rotate the mounting 
bracket around the pole. Other external antenna brackets may require a different 
horizontal adjustment.

4.

Find the point where the signal is strongest (highest voltage) and secure the 
horizontal adjustment in that position.

5.

Loosen the vertical adjustment on the mounting bracket and tilt the antenna slowly 
up and down while checking the RSSI voltage.

6.

Find the point where the signal is strongest and secure the vertical adjustment in 
that position.

7.

Remove the voltmeter cable and replace the connector cover.

RSSI BNC
Connection

Informational Note:  

Sometimes there may not be a central lobe peak in the voltage 

because vertical alignment is too far off and only two similar peaks for the side lobes are 

detected. In this case, fix the antenna so that it is halfway between the two peaks.
