Excuse me Gary. I don't bother with a computer (GIGO) program to teach me
what I learned by experience.

What makes you think I am talking about a modeling program? I have been
playing with antennas for 45 years. I can work my way through EZNEC, and I had
to learn that also.
Maybe you should spend some quality time with a good modeling program. I think
you will find the results agree with that vast amount of practical experience
you have.
