You mean it's very efficient at hanging in the yard?
Joking aside, I'd be interested in a *NEC file. Is it possible to
model, or is it restricted by the number of segments?

Let me clarify my answer.
The natural resonance resistance can exceed 1000 ohms
thought with the same design the resistance can be lowered
at the expense of bandwidth. These design forms can be easily
modelled with or without a dish reflector. I introduced twisted
wire into the design to overcome the reduced bandwidth of
the other design to bring the resistance down to the 50 to
100 ohm mark for easy match to existing components.
Since the impedance resistance is drastically lowered when
using the standard design on the computor I am inclined only
to use the computor as a guide in that instance. The dish
modelled consist of parallel elements which obviously would
be a bear to tilt so many inaccuracies are built in except in
the case of the assembly being tilted which I am presently
researching.
