Alan, is it possible to use more than one of the stepir antennas
at the same time with a single rig on a given frequency? Hope to
hear that station out here on the left coast when it gets going.

Subject: Super station update
Several weeks ago Stan put up the first tower of his super
station in
northern Florida. a SteppIr DB18E sits at about 98 feet. This
week has
been devoted to digging holes and pouring the concrete for the
next 3
towers. All together, this week's pours totaled about 50 cubic
yards of
high-strength concrete. The 3 towers will be placed on their
bases and
bolted down. He will be able to raise the 3 towers to their full
extention
in about 3 weeks when the concrete reaches about 90% of their
ultimate per
square inch load ratings. Once the 3 towers are up and
populated, the base
and guy anchor holes will be dug and poured for the first of the
3 200 foot
rotating towers. That tower will hold a stack of 6 3 element
SteppIrs,
which has never been done. Engineers and technicians from
SteppIr will
spend 3 or 4 days at Stan's new QTH to assemble and tune the 6
yagis so that
they will operate at their peak performance. Stan's so-called
SteppIr tower
will be featured in SteppIr's advertisements. The gain figures
for that
stack come out to about 24 DBD on all bands 20 thru 10 meters.
He will have
a tremendous signal, particularly when he runs the legal limit of
1500 watts
into them.
Stay tuned for further updates.
