Antenna Adjustment Using the real-time Signal Strength 

Monitor 

 

In the initial hardware installation, you visually aimed the antennas at 
each other. Though a good first step, this does not provide optimum 
antenna alignment, signal quality, or maximum throughput. To fine-tune 
your antennas, we recommend that you perform the following procedures 
at both ends of a link:   

 

1. 

Start the Signal Strength Monitor on one end of a link. (We’ll call this 

Side A

.) The RSSi values from 

Side B

 should be displayed in the Telnet 

screen at 

Side A

. 

2. 

Using your communications device (i.e., cell phone, two-way radio), 
direct the 

Side B

 installer to adjust both horizontal and vertical antenna 

alignment using the appropriate tools.

 

The installer should physically 

adjust 

Side B

 to the highest possible average value using the data 

relayed from 

Side A

.  A 20-second sweep of the antenna at side B, 

from left to right, and then a 20 second sweep up and down, should be 
enough to find the strongest received signal from side B. 

3. 

When the installer at Side A is confident that the highest possible 
average RSSi values are being consistently displayed on the screen at 

Side A

, the installer at 

Side A

 should instruct the 

Side B

 installer to 

secure the unit. 

4. 

Repeat this process for Side A using the steps just described. 

 

 

 
 

 
 
 
 
 

 

TIP 

Leave the antenna real-time signal strength monitor running until the 

Side B

 

antenna or outdoor unit is securely fastened to ensure that the RSSi values 
don’t change, and remain optimized.
