I've always heard the opposite, encourage lightning to flow elsewhere,
since lightning jumps through miles of air an excellent insulator there
is not much you can go to stop it except to make somewhere else more
attractive hence lightning rods.

I always tell people NOT to provide a path for lightning to flow.

Your posting supports that, thank you Bob.

In the 1980's I worked at the University of Arizona in Tucson. I
worked on telescopes on Kitt Peak and Mt. Lemmon.

Lightning was a major problem. If you Google Kitt Peak (KPNO) you can
see photos of the lightning.

I received funding from the National Science Foundation and NASA to
find solutions to the lightning problem.

We found the best solution was disconnect the incoming power INCLUDING
THE GROUND at the entrance to the buildings. Then we disconnected all
the electronic systems by pulling the power plugs out of the wall. We
had jumper cables connecting all the incoming phone lines. We
disconnected them.

We also used semiconductor devices know as TRANSORBS and gas discharge
protection devices on all the power lines in the building.

At Mt Lemmon the telescope was in a low building. We installed a 200
foot crankup tower near the telescope. There is what is known as "THE
CONE OF PROTECTION". We knew we were going to get lightning hits so we
tried to control where they were.

Lightning is totally unpredictable other than the mountain tops will
get hit.

Hi Paul !

I wish I could get on the 40m net tonight, but I took a direct hit
in a lightning storm a few nights ago. It burned up my unun,
coax, and blew the coax out of its PL259 on back of the tuner. My
rig was disconnected, as always, but it also wrecked the wiring in
my test bench.

Good luck this evening.

Hello All,

Wayne will not be able to call the 40 meter net tonight. I will
give it a go for him. My old note stuck up here says 730 local. Is
that correct? If not please let me know. If there any SKCC
Centurians, Tribunes or Senators out there let fly your number. I
am only 6 out from having my Tribune.

CU tonight on 7122 we can go later if it would work better. let me
know de Paul N0NBD
