Chapter 5 - Antenna Alignment
This section covers the antenna alignment process to achieve the best radio link performance.
The goal when positioning the unit is to align the antenna for maximum signal strength. In
addition, TOTAL radio units incorporate RSSI Audio Tone to simplify the antenna alignment
process. The RSSI Audio tone is convenient to use and adequate for most installations.
A built-in speaker is provided to monitor the RSSI Audio tone. The TOTAL radios can be
aligned to any angle with in a +/- 30 degree span for a given polarization.
Note:
This chapter is not applicable for the TOTAL access points and airClient
TOTAL (sB345) as they do not have the RSSI Audio Tone feature.
Establishing Association
On short links where the remote radio is visible, point the unit in the approximate direction
and use the site survey tool to find the radio at the far end and establish a more precise
association. The integrated antenna is located on the front side of the enclosure.
For longer links where there is no visibility, use the GPS coordinates of the unit at the far
end and calculate its compass direction from the near unit. Point the unit along that precise
direction.
Once the association is established, you can align the antenna using RSSI Audio Tone from
the built-in speaker on the unit. The RSSI Audio produces a tone ranging from 523 Hz (low
pitch) to 2093 Hz (high pitch) that is proportional to the received signal level. The RSSI
Audio Tone provides instantaneous feedback as you move the unit with built-in antenna
within the enclosure.
