As we all know, the atmosphere greatly affects the propagation
of radio waves, with all the various layers, and the effect of the
Sun and sunspots on propagation through the atmosphere.

Is it therefore not beyond the bounds possibility that this same atmosphere
affects the initial propagation of radio waves away from our antennae,
and that somehow is the reason why short antennae are poor radiators
compared to antennae of significant (1/4 lambda) fractions of
a wavelength?

I know that I have attempted to discuss this before and been met
by the hidebound rednecks of Yankland, but it is a question
of interest to me, and not a troll.
=================================================
I doubt if distant conditions affect the origin. Does the archer's bow
"know" whether the arrow will be striking the target or landing in the dirt
150 feet beyond?

I am only a talented amateur but I think with an antenna, the wavelength is
best matched by the antenna aperture. This is not the case with short
antennas.

What do you think?

I intended the atmosphere immediately adjacent to the antennae.

The standing wave caused by reflection from the open end of a short antenna
will not cover a full quarter cycle, and therefore the radiation must be
reduced
accordingly.

But that fits in with my opinion that the atmosphere / environment/
lumeniferous aether / or
whatever needs in some way to be excited or twisted by the EM field of the
antenna, hence
my suggestion that you quoted above.

Nope, and easily shown to be false.

Your opinion was disproved about 100 years ago.

Perhaps that is so but it isn't a conclusion I would immediately draw.

While it might be an interesting discussion topic, knowing with certainty
(one way or the other) would not affect how we work our compatriots near and
far on the radio.

The essence of amateur radio, one of the many things that distinguishes it
from CB radio,
is an insatiable technical curiosity.

Too bad that curiosity doesn't lead to following the URL's posted by
many that contain extensive technical information.

I agree. I have an iPad and I drive my wife crazy when I leap to it
whenever there's a question. (I cannot restrain myself.)

That's good. If not for the iPad, I'd need to invent another way to
drive her crazy.
