The less ground conductivity the higher is the antenna elevation radiation

Excellent work, Cristi.  A suggestion for this last part of the 
analysis.  Rather than look at the vertical angle where the radiation 
peaks, look at the field strength at some chosen low angle, like 10 
degrees for various soil conditions.  Now, we can see a dB value.
Another thing I've been doing with EZNEC is saving computed pattern 
traces for various conditions and then recalling them all on a single 
plot.  In this way, it's easier to see the effects of a change.  And it 
is also possible to move the cursor from one curve to another and see dB 
values.
