Antenna Alignment Commands
set aad enable local
Enables display of the local SNR. Local SNR is the SNR measured by the receiver at the near end.
set aad enable remote
Enables display of the remote SNR. Remote SNR is the SNR as measured by the receiver at the far end.
set aad enable average
Enables display of the average SNR. The average SNR is the average of the local and remote SNR.
set aad disable
Disables Antenna Alignment Display (Ctrl-C also disables AAD).
Link Test
You also can use the Link Test option of the management tools that come with the radio unit to analyze the radio
link quality. The Link Test option lets you display the radio signal strength in relation to the noise in the signal
path. If required, you can interactively optimize the antenna alignment with the Link Test, by making small
modifications in the antenna orientation.
The Link Test provides SNR, Signal, and Noise information.
Link Test stops when you close the Link Test page.
Alternatively, consult a professional Antenna Installation Service to optimize the antenna alignment.
Antenna Polarization
Outdoor antennas are standard-mounted for vertical polarization.
In some cases, you might consider mounting the antenna for horizontal polarization; for example, to minimize the
influence of cross-talk between antennas when:
• You plan to mount multiple directional antennas to the same mast.
• Your wireless link receives interference from a vertically polarized neighboring installation.
Note: For optimal wireless link performance, you must always verify that the antenna polarization on both ends
of the wireless link is the same.
