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.
