Robert, Jeff and All,
Having jsut read the post below, reminds me of some (literally)
"hair-raising" experiences of mine. While in the Service (U.S.
Army) and stationed at the Stratcom-Western Hemisphere
Headquarters at Ft. Huachucha, AZ., in 1970, as a communications
specialist, I had the great opportunity to witness Southwestern
Arizona's finest and most impressive monsoon-type summer
storms. There was an insulated guy wire between two utility
poles near my barricks, and I observed the same phenomena
that Robert mentions below. I decided to try some experiments
on my own. I gathered up some 16' 2 X 4's, some wire, and
about 50 metal coat hangers. I fabricated a home-made
horizontal insulated dipole antenna, with the coat hangers evenly
spaced over about a 100' run of bare stranded copper wire, which
was elevated between two 30' high wooden supports. I used
rocks, ect.to support the bases off the 2 X 4's, and used 100 lb.
test monofiliment fish line to anchor the ends of the supports. At
one end, there was a convenient clearing on the desert floor
(surrounded by the native giant catus that grows very prolifically
there.) This clear area was a mound of earth (home to a giant red
ant colony.) The opening of the mound made a suitable place
to locate the base of one of the 2 X 4's, with a little digging.
The other vertical support took much more work, with lots of
desert boulders rounded up, to fashion a base on that end.
About 3 days after I had the whole thing set up, a NOAA
category 3 rating storm moved up from the Gulf of Mexico, over
the area of the Fort. Many mulitple cloud-to-cloud, and cloud-
to-earth strokes lit the darkened afternoon sky. Some of these
were of very long persisitance, lasting for approximately up to
2 seconds in a single stroke path. One stoke struck a 66 KV
overhead transmission line about one mile away. I believe I saw
a greenish ball lightning following that stroke, which moved
along the wire for about 10 seconds. Another stroke hit about
500 years distant from where I was standing, watching my
antenna for any signs of arcing. I decided that it was best to move
my _ _ s indoors a.s.a.p. While I made my retreat to the barricks
which was about 100 yards away, WHAM-BOOM! All the air
around me seemed to sizzle in a blinding flash. I recall that I felt
like I was hooked up to a 500KV Van deGraaff generator. When I
turned around to look at the antenna, it was gone. Not a trace left
in sight. The next day, I went out to where I had built the antenna.
I could find now wire, no coat hangers, no 2 X 4's. The support
end (built over the ant hill,) looked like someone had taken a big
torch to the whole area. The other end, with the pile of boulders,
revealed that the rocks had been scattered in every direction. There
was a blackened area of ground where I believe that support used
to be.
Near as I could figure, that insulated antenna must have taken a
direct hit. And as Robert pointed out, that event left an
indellable impression on me, for life! BTW: Two weeks later
and there was still no sign of the giant red fire ants at "ground
zero."
