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.
