Re: NEC-LIST: What am I doing wrong and/or don't understand ?

Good day Arie,

The A=4 value is something I remembered using with NEC4, but
I see the NEC4 manual doesn't list it either. It gave the
same results as A=1 however. When you were first talking
about average gain, you should have said that you were using
a different gbround. To me, it doesn't make sense to
compare the individual gain values over one ground and the
average gain values over another.

"Theta" is the standard polar coordinate angle measured off
the +z, vertical, axis. Its physical meaning is that it is
the angle from the +z axis to the radius vector in a
vertical half-circle. The plane of the half circle is
rotated from the x-z plane by the angle "Phi". With this
picture in mind, you can see that only 0<=theta<=180 deg.
makes physical sense. If the code treats theta=-40 as
theta=+40 deg, then a sweep in theta from -90 to 90 deg is
the same as seeping theta from 0 to 90 twice. This would be
a waste of time, and I'm not sure how the averaging would
work. It seems quite possible that the result would be
double what it should be.
