I am not entering this debate one way or the other. I do have a

How do you determine when the ionization threshold has been reached?


Corona invariably causes a glow at night. I have witnessed
such a glow but not very often. I came across a calculation
of the ionization threshold in volts yesterday while on the
web. I don't remember the exact figure but it was in the
thousands of volts for average air conditions and varied
with the geometry of the conductor.


How many systems have you looked at Cecil where you were right next to
the antenna while this was going on?

More than I have or many times less?

My bet is many times less. Probably none.

I'd bet you never were on a 300 foot or taller tower or on the roof of
a building, and I'd also bet you never had multiple antennas of various
tyoes to compare.

I'd wager all your data comes from what you picture in your mind.
