Wap 60G problems in winter, disconnects

Yesterday evenning started first freezing weather, temperature below -5st.C and the units started disconnects and connects. Rapid changing in signal, RSSI…Nothing other happened, nothing new in the way. It seems like there is problems with frost on the units.
What are experiences of others?

Distance 180m, channel 66000, firmware 6.44beta28

Distance / Channel / ROS Version?

I am quite sure that lower channels are more efficient for WAP antenna

I also tryed 64800 and it was worse..why you think lower channels are better?
signal before freeze winter was 80, now is worse…

is there any snow on front cover? Maybe device has alignment problems?

I read somewhere maybe here https://fccid.io/TV7WAPG60AD/RF-Exposure-Info/MPE-Test-Report-3521243 that antenna has better gain in lower channels some dB more
