Step 14: Align the Antennas
Antenna alignment is the process of physically aligning the antenna of the radio receiver and transmitter to have the best
possible link established between them. The antenna alignment process is usually performed during installation and after
major repairs. If you are installing external antennas, refer to the documentation that accompanies the antenna for
installation instructions.
The device has an audible antenna alignment tool that can be activated by plugging in the supplied RJ11 serial dongle. It is
audible upto 30 minutes. The CLI command enables both audible and numerical feedback as the CLI shows the running
Signal-to-Noise Ratio (SNR) values twice a second.
The output from the beeper for antenna alignment consists of short beeps with a variable interval. The interval changes with
the SNR level to assist in correctly aligning the antenna. An increase in signal level is indicated by a shorter interval between
beeps and a reduction in signal level results in beeps longer apart.
The alignment process averages the SNR, which is represented by an average length beep. When a higher SNR is received, the
beep period becomes shorter. A lower SNR results in a longer period between beeps.
When the antenna is aimed, the beep intuitively represents whether the SNR is rising or falling. The higher the SNR rises, the
shorter the period of the beep is heard and the higher the frequency of the beep. When you change the position of the
