Over a long period this past spring and early summer, we had an exact 1:1 correlation between SNR and rain density.

I eventually scaled the pole out back, found the breach, and taped it up. Rain no longer buggers things up nearly so much here now.

But then there's still the 20 or so poles (from the cross-connect box at the underground feeder cable) before the bundle gets to the pole out back here.. each with their own splice / bridge taps for a pole-mounted leaky F2 junction box..
