My SO is unusually wary of lightning and lightning strikes. If
there is the slightest hint of lightning or thunder, she reverts
to the air gap method of lightning protection. If there are no
wires connected to a piece of electronics, then it is most safe.
Doesn't help a lot in our business, but that is what she does.

I have been working with this AS3935 franklin lightning sensor
for about 6 months now and learned so much more about lighting
and its projected energies and possible frequencies its
amazing how this little sensor can detect distance and the
amount of energy BEFORE it strikes.
So,armed with this ability I am solely working on a design
along with IR sensing to help mitigate damage to a site during
a storm.
I am still working on the timing to be able to shut down power
to the gear outside for a time period at which if lightning is
still present remain off till storm passes.
End of Run sites are the worst but knock on wood after a year
or 2 of planning and cleaning up the existing grounds
everything seems well.

Snake oil for sure. You can't stop lightning strikes
because of the volume
of energy and short time period. If you put one of these
devices on a fully
grounded metallic tower, it would most likely take a strike
to ground. Of
course, if you ground your metallic tower properly, it is
like a giant
lightning rod, so you are out the money for this "topper".
By the way, on
tall towers, lightning doesn't necessarily strike the top
anyway - it is
almost never straight vertical and may be at a 45 degree
angle to the side.
But let me ask you this - if all the pine needles in a
forest can release
ions (which they can and do) or all the blades of grass on
the prairie, why
does lightning still strike there?

I think snake oil. You?
