My place was hit on 6/30 with an apparent microburst that did tremendous
damage. Many trees are down and one large white pine came down right
across the west guy anchor of my 130 ft rohn 45 144 MHz tower. This was
a tree that I had identified to remove as soon as I had a chance. When
it fell, it snapped off the top of the rock anchor. They have a rated
working strength of 14,000 lbs, but I am sure the falling tree force was
much greater than that. With no guy attached the tower just toppled over
and laid out all 130 ft across the tops of trees. The equalizing plate
and part of the anchor is up in a tree. It is a total wreck. The H frame
on top has been ripped apart along with the four 17B2 144 MHz yagis. The
famous LVA, an array of 16 x 5 element yagis spaced along one tower leg,
was also on the tower and has been destroyed. I was in the process of re
aligning the LVA to aim towards ND0B in N. Dakota in an attempt to give
him his last state on 144. Now there is nothing left. As the yagis fell
through the foliage canopy, the elements have been cleaned off or
severely bent. Many booms are ripped apart or bent. There is nothing
salvageable from the quad array of 17B2s. They are all destroyed. The H
frame is destroyed as well.
I was not here when the storm came through, but witnesses said it was
very frightening and the winds came from many directions. My neighbor
has about 40 uprooted trees. I suspect a microburst from the direction
that I see fallen trees. My wife arrived home just after the storm and
called me. By the time, I arrived, it was just after 9PM and getting
quite dark. I knew something was wrong when I could not see towers on
the hill while driving south along the lake. Normally the towers are
very visible. I could not sleep all night, and, at dawn, armed with a
big chainsaw, I drove the truck up to the VHF shack. The scene is
sickening, with the entire tower laid over the trees and bent like a
pretzel. It is being held up on one end by a guy wire from another tower
that somehow managed to stay up! That guy is under tremendous pressure.
I am not sure how to fix all the damage, and save tower #2.
