That's quite the project that Stan has going !
I do have to ask one thing....If the primary objective is EU, couldn't
the same effect be achieved with 2, 4 or 6 strategically-placed 140'
Rohn 25 towers and a long-boom wire beam ? Seems that would cost less
and probably be more robust and maintainable in the long-term.

RE: The Big One
I am encouraged by Peter's comments having to do with terrain.
Actually the antenna is 6 elements on a 110 foot boom instead of five on
a 100
foot boom. On FLAT ground the antenna would probably not be as good or
versatile as a stack of 3 element yagis if you had the top one up about 200
feet. From my location this antenna should be that stack into Europe
which is
80% of what I would care about for this antenna. Also, part of this is
that
there are plenty of 3/3 installations and this is a much more challenging
project..
The versatility problem will be covered with the current 3 element yagi
which
will be moved to a new location on the mountain top.. To give you an
example
of the terrain in one direction, the new location for the 3 element yagi
at a
height of 80 feet is predicted by HFTA to be a better performer to JA
than the
six element one at 135 feet. It appears to me that in some instances
the only
way I can get any real advantage by phasing antennas would be for them
to be
side by side instead of vertically stacked.
