When a source of interference is identified and when the level and frequencies are known, the

next step is to avoid the interference. Some of the following actions can be tried:

Change the RF channel to the one away from the interference source

Change the polarization of the antenna; try to change to a polarization different from

the interferer.

A small beam antenna may helps. (Such as some grid or dish antenna, align the

antenna in to the particular direction will reduce the affects from the interference

source) This solution cannot help when the source of interference is right behind the

remote site.

Before checking for interference, ensure all the hardware works well and configurations are

correct. The path analysis, cabling and antennas should be checked as well.
