from time to time all customers were out, and checked cable and antenna, the signal level is minimal. I work at 2.4ghz with a 14dBi antenna, 120 degrees. The team was working well since it was installed 4 months ago.

Do not actual sea a question? If it was your users were disconnecting, We found on the R52 radio cards that the connection onto the card is not very good. Fix this by putting piece of tape to secure cable and plug onto radio. No more problems. Change most of radios to R5H, connector much better.
