I have a strange case that I wished to check with you ladies and gentlemen (...or "animals" - we've never established a term for AF members?):
I have a tower where we're using 3.65Ghz PMP450 with ABAB frequency re-use (recent installation). Users wouldn't stay connected to the N sector; I ran an SA and it was clean, other tests looked good. I was thinking over possible causes and remembered that there's a big elevated water tank ~3000ft S from the tower, whose surface could reflect signals from the S sector (that is on the same frequency as the N AP) towards N directions, at an angle that would be in the main lobe of almost all the customers. I don't know passive-reflector math enough to estimate how strong that reflection would be, but has anyone seen such a case before?
