As my Elmer W4MLE told me in about 1961, Antenna and Propagation Theory are just that, theory. Now waiting on my KX3 as we fly to IS0 next week for 15 days. Listen for IS0/DJ0RD 😊

Much less so now than in 1961 ... for both.

Hi Bob,

You and W4MLE (SK) are both correct about antenna and propagation
theory, based on the universally accepted definition used in science and
engineering:

Theory: a well-substantiated explanation of some aspect of the natural
world, based on a body of facts that have been repeatedly confirmed
through observation and experiment.

Re: Entertaining Tales

If the initial post was to indicate that theory and fact were not well
aligned (That is the way I took it), then I would like to point out that
much of what was only theory in the 1960s has become more embodied in
fact in later years.

There is still a lot of mystery and mystic in propagation and sunspot
prediction, but a lot of antenna theory of the 1960's has been hardened
in science. The foundation of electromagnetic radiation is soundly
grounded in Maxwell's Equations - but they are a difficult study all in
themselves.

I give a lot of credit to LB Cebik W4RNL (SK) for his modeling skills
and studies into antennas of various types.

LB was a friend of mine and an amazing guy. He also was a charter member and frequent presenter at our East Tennessee DX Association, and (if not already known by the list) an Elecraft K2 owner.

Exactly right. In other words, principles that have been proven by the
scientific method. As a scientist, I have always believed that if you
think there's a difference between theory and practice, you don't know
enough about one or the other. That is, you don't understand the
problem, or you don't understand the known science. Most REAL problems
and systems are complex, whether technical or political or financial or
business.

As Don said, there ARE things that we as a civilization haven't learned
yet, and the complex effects of solar radiation are one of those things
we know SOMETHING, but not everything, about.

On the other hand, there are all sorts of things, everything from
science to politics, to interpersonal relationships to how business
works that we as individuals have not taken the time to learn, but that
ARE clearly understood by those who have taken the time to study them.
And the fact that we as individuals haven't yet learned them does not
make those things any less true.

How antennas and transmission lines work has been clearly understood by
those who have taken the time to study them for nearly 100 years. But
for someone who hasn't done that, it can seem like black magic.

"How antennas and transmission lines work has been clearly understood by those who have taken the time to study them for nearly 100 years."

Quite a small group then. Few with an interest in the subject would live long enough.
