4 min. cicles

Has anyone had this problem before?
One of my custumers near an airport (5.2Ghz) has been working fine over 2 month, last week he start having a lot of regs. After realigning several times i discovered it stays registered for exactly 4 minutes and then go off for exactly 4 minutes…It only happen with this custumer.

Another curius thing is, during this 4 minutes period it remains registered, if I make a link test, it begins with 100% both ways, then the download percentage begins to go down until 10% then get scaning for 4 minutes again…

could be a strong RF signal (RADAR) that is de-sensitising the unit. Are you using a reflector.

We have kit on 5.7 in the airport, works fine…

need to go down with a spectrum analyzer…
