Well, yeah, you have a point Wes... slightly-embarassesd-grin

How did you compute the impedance of the "either"?

I have heard it given as, "speed of light times mu naught."

However, I have not examined proof of this, and actually, that is claimed to
be the impedance of space itself (a vacuum), "air" maybe slight different.
Anyway, I adopted it simply because it seems to be accepted--do a "google
search" with the search terms:
[ impedance either 377 ohms ]
You will either find your proofs there, or not....

Warmest regards,
John

"Balun" is a contraction for "balanced-to-unbalanced". It converts an
unbalanced drive source (such as a grounded coaxial feed) into a
differential drive drive source that is completely floating with respect to
ground or any other common point.

Even if there were such a thing as the 'ether' (there isn't; elecromagnetic
waves don't need a medium to propagate), your antenna would not be
classified as a 'balun' just because it transforms your electrical feed into
electromagnetic waves. It would more accurately be called a 'transducer'
because it transforms energy from one form (electrical) to another form
(electromagnetic). One of the characteristics of a transducer is that it has
input coupling properties as well as output coupling properties, so in this
respect part of your statement is sort of accurate - the part about
impedance matching.

Actually they do. It is generally accepted that EM waves
cannot propagate outside of the universe precisely because
of the absence of any structure (medium). Our medium of
space is thought to have at least ten dimensions.

Dear Richard, if you have some theory of how EM waves can
exit the universe, please present it.

Well, I know you asked Richard....
But, I think there may be a way if we tear a hole in the "shielding."
Yanno, even if you can get a Klingon Warships'shielding weakened enough, ya
can get a photon torpedo through!!! innocent-look
