lo there…
so … added a new 433 board with a r52hn + 2 cable lmr400 connected to a ubiquiti sector antena 15dg120 (2.4 sector)
board is with latest ros avaiable… 5.14… board has a 24v 1.6amp to power it..
added a few clients in it .. and after a few hours… started seeing toons of no beacons received…changed channel …samething…
any help?! anyone?

Looks like the noise floor is fried.
Do you have any other equipment you can verify this with?
Could be a bad CPE or R52HN.
will try with other card to see if samething happens…
that r52hn is new…
I had an R5HN fry after it had been tested on the ground for a week or two. Turns out there was a tiny bit of the outside aluminum insulator touching the center conductor on the LMR400 I used on the tower.
I now test the entire AP as an assembly.
