Hornets cannot fly!
I find interesting and intriguing the discussion: understand how
things works is of course very important and leave to other to state if
this has to come before or after experimentation.
My first approach to MW was dictated from hirony.. how can such thing
work? After almost 2 years of use I still have doubts of interactions
between all the wire on my roof and the MW itself but finally is a gear
that makes some work. Under some circumstance better than standard wire
antennas, in other cases worse but today almost all my LF/MF receptions
are made with a MW.
The idea that the E probe is similar to a cap plate against the
universe can explain some aspects if not all.
What about the same idea applied to a TX antenna? (antennas should be
reversible items..)

I don't know if my previous posts arrived but I still prefer to think
that a "small" antenna is one plate of a capacitor and the rest of the
universe is the other. This then enables the spacecraft antenna to
work.
The universe is not a great big empty space!
