Microwave installs take weather into account on allowed SNR at install time.
He's on DSL (copper)
I'm on 10.5GHz Microwave, and time of day is not relevant. However I'm
at 13km approx and very heavy rain will drop signal by 3dB. Extremely
heavy snow on Woodcock hill has happened once in the 2 years+ I've had
it. (I suspect built up on the Base aerial, as it is not heated) and I
had no signal for over an hour. I've never lost the link due to rain.
I've 2 x cable modems on it set to give 10Mbps.
You'd need much longer paths than any typical CPE uses for Microwave
day/night effects. Long path over sea can be a bit strange if you are
not high enough (Scatter?).
I also have 4 Ku band LNBs (one motorised), one 2 way sat 18Ghz up,
11Ghz down and one C-band LNB. Heavy rain is the only significant issue.
I once lost even Sky on 80cm dish for 10mins, The rain was so heavy
(near lunch) that sky was black and we had 2" flooding in 15mins. And
I'm on an open hillside :-) At one place in the garden the water was
bubbling OUT of the ground due no doubt to pressure higher up the hill.
