Chuck,
You are music to our ears... :)

About 35 years ago Mobil Radio Technology had an article about static
cat types of dissipators.
They had a pen recorder connected to a current shunt and they measured
the current flow of the dissipator to the cloud. It would build and
build and then there would be a nearby strike. I think the pen recorder
was also connected to something that would show the strikes.
You could actual measure and record the air terminal doing its job.
They had lots of other content showing that the air terminal eliminated
much of the potential difference between cloud and ground in its
immediate vicinity. That was a convincing article. This web site is
trying to sell me a trombone.

Sounds exactly like an "air terminal" / lightning rod / static cat plus an
incredible amount of hype. So yes, virtually all commercial towers have an
air terminal to dissipate static charge and discourage an actual lightning
strike. Plus a heavy gauge down wire.
It takes about 2 seconds looking at their web page to see this is 99% snake
oil. It's the QVC cubic zirconium of lightning rods.
I don't know if a static cat actually works better than a simple pointed
rod
(air terminal), but at least there are some physics based reasons to
believe
that a bunch of pointy things might work better than one pointy thing.

I had a conversation with another tower owner tonight regarding active
lightning suppressing.
https://www.preventlightning.com/
The theory sounds good, and I've seen similar things installed on at
least one other tower. My question -- does it actually work? And if
so, why is it not standard fare on towers? If I'm putting in a 160,000
commercial tower, why wouldn't one of these things just go on top of it?
Thoughts? Chuck?
