Panning Type 42 Outdoor Unit Using STMON
Antenna Alignment
Once configured and installed the ST Antenna /ODU will need to be panned to optimise the
RF link quality- SNR, signal strength and fade margin.
STEP PROCEDURE
1. If pole mounted place and tighten a tie wrap immediately underneath the pole bracket
to prevent the assembly sliding down the pole.
2. Loosen the outdoor unit fixing bolts sufficient to allow the antenna to rotate around
the pole.
3. Using compass bearing point the antenna in the direction of the CT (base station)
antenna.
4. Select the Radio Data tab to display ST data. For details of the display see STMON
Display Descriptions
5. Wait for both an uplink and a downlink to be established. If The ST Fails to acquire
check the display to see that the ST has been configured correctly and there is
sufficient signal strength and check compass bearing for CT. Check that the antenna
does not breach the deployment guidelines.
6. If ST supports voice. Connect a telephone to the ST and make a test call
With the call in progress read and record the following from STMON:
a) The receiver power in dBm.
b) The transmitter power in dBm.
c) The downlink SNR
7. Click the Advanced button. Select the Radio Analysis tab. Click the Peak Meter
Button (Alt+p) . The peak meter displays the current downlink signal strength and is
used when panning an antenna to find the strongest signal.The peak downlink signal
strength displays the maximum downlink signal strength measured since the start of
monitoring and can be reset using the Reset Peak Level button (alt s).
