"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.

My antenna seems to match the impedance of my transmission line (50 ohms)
to
the impedance of the either (370 some-odd-ohms), isn't that a balun?
