Rain rain rain.. We need more real live testing. But.. Todays situation about 40-45mm/h link was down for 4 minutes going from -56 to -70 in few seconds. The wet antenna takes -4dB!! Link length 1300m.
The link nearby with WAP for 400m was doing well all the time loosing approxiamtely 1-2 on RSSI scale looding from -66 to -68, and already working as before the rain. LHG is 15 minutes after rain still -59 and once dry has to come up to -56.
MCS and also signal is VERY unstable when link is under load, signal is jumping between 20 to 100 approx. each second, same as MCS - between 1 up to 8
Also, after a load, MCS will remain at low values 1-2 same as signal - from 80 before load to only 20 after a load
