From the above one can see that approx 15 dbi is the most

Hi Art,

With 2 minutes of modeling (and using the only 3 element yagi model
offered by EZNEC for FREE), I got 15.14 dBi.

Why does a gaussian array need 10 elements to get less?

Has there ever been a definition of a guassian array. From the best I can
figure ART just claimed it otbe a bunch of random lengths mounted on a boom
but every time I see a model he presents its just a mucked up yagi.

Let us talk common sense. Remember its origins is based on a static
field
where all of the field was in a state of equilibrium. Equilibrium can
be seen as
a cluster of elements where the current flow in all elements flow in
unison
and change direction in unison. There is no need to add a boom in the
definition as a supporting framework since we are looking at radiation
results.
On the arrangement given I forced the elements to take up a horizontal
or
planar position away from the natural formation form which is
approximately
1/2 wave cubed. When you refer it to a "mucked up Yagi" you must
understand
that the Yagi is primarily set up to focus available radiation by
redistribution,
where as with a Gaussian there is no focussing or relaying of energy
by coupling.
Later I will investigate maximum radiated area of the radiated field
with
respect to element arrangement rather than providing a maximised beam
length.
