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?
