It changes so much that when predicting lightning performance of power
lines we have to take into account the diameter of the corona around the
wires when computing the characteristic impedance of the wires to
properly predict currents and voltages.

Given your familiarity with lightning and power lines I have a
related but more specific question, please?
We live on a 10 acre lot in the woods. The lot is 360 x 1600'.
Along one side is a 70 x 1600 right-of-way on which sit a couple
of tall poles for what I believe are 5 year old 14,000v lines.
I am planning to locate my tower at the far opposite edge of the
property 300 feet from the poles.
I am also about to initiate construction of an all-steel 40x60'
home, the front 40' side of which will be about 200' from the
poles.
Am I correct in presuming that while the poles are likely to
be at least as attractive to lightning seeking to discharge
as my 60 foot tower (plus mast) that they are too far away to
impact anything I do at the house or tower?
Thanks! & 73, doc kd4e
