D.5 Troubleshooting
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 WinLink1000-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.
