If the link is not within the acceptable limit as defined in
Evaluating the Link
,
check the following:
Verify that both antennas have the same polarization (horizontal/vertical).
Check all the Airmux-200-AIND cable connectors for faulty connections.
Verify that there are no obstacles in the Fresnel zone of the antenna path
such as large buildings, trees, etc.
Use a spectrum analyzer with suitable sensitivity to measure the signal at the
distance between the sites.
If nothing improves the receive power level, check the overall link.
Reduce the distance of the link. Move the equipment from one site closer to
the other site where it is possible to actually see the antennas with the
naked eye.
If you now get the expected receive signal level, you can assume that the
equipment is operational, and the problem arises from interference between
the sites.
