Dear MK:
You speculated about the performance of some antennas. Performance
includes antenna gain distribution and ionospheric propagation. The
programs that I, and others, mentioned would provide you with meaningful
performance numbers. I thought that you might wish to know the performance
of the antennas you discussed over the paths mentioned (and other paths).
Such knowledge might reduce the uncertainty of the speculations. It is an
engineering sort of thing. Not all are enamored of changes in entropy.

Please disregard my suggestion. It was not matched to your desires.

Dear MK (NM5K):

I do not understand. Why speculate? In the over forty years
that I
have been involved with the prediction of HF propagation, huge
progress has
transpired in the ease with which one may investigate the issues that
seem
to be of interest.

I'm not sure I understand. Why speculate about what? Verticals vs
dipoles?
Or do you mean propagation only? Or you talking about qround quality
per a
certain area?

Today, one may download and run a series of computer programs
that will
provide statistically significant answers to your questions. The
programs
have evolved over decades and are refined.

As Reg might say: ready to run.

Numbers tell the story. Enjoy.

Tell what story? I might try downloading them, but what is it I'm
trying to find out?
What are my questions? I'm not overly keen on downloading a potentially
large
program, I then have to install, and take up more room, without knowing
what it is
I want to do with it, or even what it does... You are leaving me in the
dark too
much as to what this program does...Even they don't give a real
description.. MK
