Alan, seems like grounding would be the least of your issues, I
mean it's being built in Florida right? Almost the whole state is
soggy and with climate change, it will only get more soggy in the
future, Jim WA6EKS

Hello Tom, Not to worry about station grounding. A thorough
plans was
worked up by several electrical engineers. Nothing can guarantee
that the
towers won't be hit, but as much as can reasonably done, has been
done.

Alan,
I hope his safety grounding system is as elaborate as the
antennas. they do
get thunder storms there don't they? <GRIN
Sounds like entirely too much fun.

As you all know, I have been working with Stan, KH6CG/W4, to
design and
equip his super station in north west Florida. Among the
antennas that
are
being installed are a dozen SteppIrs in different models.
Currently, and
for a brief period only, Stan has a DB18E on a 85 foot tower.
By the time
that you add the rotor and mast, the DB18E is up at about 98
feet. The
next
tower to go up in about a month, will be a stacked pair of
DB42s, the
largest SteppIr model. The bottom DB42 will be at 60 feet, and
the upper
one at 120 feet. After that, there will be a stack of 6 three
element
SteppIrs going up on a 200 foot rotating tower. Then there will
be
several
more SteppIrs, probably DB36es on towers for each of 3 guest
bedrooms. I
will report back on how reliable this sizable group of SteppIrs
turns out
to
be. We fully expect the yagis to perform well, and without
problems.
However, just in case there are any failures, Stan has purchased
spares of
each model which will be fully assembled and ready to go up in a
moment's
notice. Stay tuned.
