[Antennas] MODELING_PROGRAM_SIMPLE?

[George K]

Let me ask this question again with a twist.
First thank you to all that responded to my question asking for a free antenna modeling program.
I down loaded the MMANA modeling program and I don't have a clue at what it is asking for or what it's output will be. I guess I'm just not with it.

Is there a MODELING PROGRAM that asks for the length of the dipole, height above ground, and then outputs the polar display of the lobs vertical and horizontal? Maybe the feed impedance as well?
The MMANA is talking X, Y and Z??? Then seems to give a vector display of which I don't know what it means.
This program looks too complicated for me?
All I want to know is how the lobs look at various dipole lengths.
Thanks.
George
