Is the noise a 60 cycle hum ? or just noise in general? qrn or qrm?
I still think that it is a grounding problem .

I could be wrong but it sounds like thw same problem I had untill I
expanded my ground system and tied it to my utility (meterbase ground)
Then all the noise, vanished....
My 2 cents

Another reason is that as things dry out, the
connections to the pole Losen up , as the pole
shrinks, relative to the hardware. and- induction
to , say Crossarm Braces , can cause arcing ,
between those braces ! A way to check for this is
to give a pole a swift hit with a hammer. If the
noise goes away, or is changed, probably is loose
hardware on the pole . A thought for your
consideration- Jim NN7K

What is it about general "noise" that makes it go way down during rainy
weather?
