17 mile link, 11GHz, 3' dishes- it's worked fine for years and over the past few months there has been an increasing fluctuation with signal quality. SAF support suggested we were too high on one side and actually lowering it would help, it didn't change. We've verified LOS, even switched out to a DragonWave 11ghz pair of radios and it exhibited the same behavior as the SAF. We then moved one side of the link to a different tower about 6 miles away (still makes overall link 17 miles) and we're getting the exact same behavior. In years' past the signal was consistent, now we're seeing this:
[cid:[email protected]] Am I missing something? Same behavior with two different radios, frequencies, and towers. There are no environmental conditions like moisture, etc. that are obvious culprits.
