Steve, before I quote the wrong numbers for wind loading, let me get them
and get back to you. The stack of 4 6 element 20's + 4 of the 4 element
40's on the same 200 foot rotating tower also adds quite a wind load.

Holy Smoke! What is the wind loading on such a monster antenna.
I might question the wisdom of putting up something that large in
Florida not only because of hurricanes, Hisacanes, but general
lightning and thunder storms as well. That's a whole lot of
metal up there. But what a thrill it must be to work such a
station! Jim WA6EKS

Subject: 80 meter stack
Good afternoon all. As you all know, I am working with KH6CG to
build his
super station in northern Florida. From time to time I have
mentioned what
we have been up to in preparing for one band or another. The
latest
decision is to put up a pair of full sized 2 element 80 meter
yagis. The
lower of the pair will be installed at about 90 feet, and the
upper one at
200 feet. The gain for this stack of 80's will exceed 10 DBD,
which is
unheard of for 80 meter antennas. When the station is finally up
and
running, I will report back on how the various stacks are
performing on each
band. Stan and I are excited beyond belief.
Happy New Year everyone
