You mean the radiation from an antenna driven by a radio transmitter?
It doesn't emit electrons, but it does emit photons at that radio
frequency.
Go find a book on electromagnetism and fields, but be prepared for
calculus level math in that book. I took such a class 30 years ago, and
got a "C", and remember even less now. A high school physics book might
be enough depending on your needs.


The current (May/June) issue of QEX contains the article:


Electromagnetic Radiation: A Brief Tutorial


It contains equations but no calculus that I noticed.


"magnetic electrons emitted from a radiator" isn't mentioned, but
that isn't a surprise to most people.

Jim, you have no legitamacy in the subject of radiation, your past
posts prove that. On top of that you do not talk for most people as
you intimate.
You haven't yet capitulated on the static subject or negated the truth
of the mathematics and examples supplied. Just stating consistently
that you can't this or you can't that just doesn't elevate your
stature.- Hide quoted text -

Some have stated that 377 ohms is a ratio. I don't understand that
assertion
since I understood that a ratio is not confined to a specific unit and
in fact
does not have units. I am aware that the impedance of a particular
atmosphere is 377 ohms but that is certainly not a ratio. Some say one
must have a knoweledge of calculus to understand radiation. Another
declares he read a book on radiation that did not use calculus which
is just as well if one becomes careless with terms such as a ratio.
But no matter, this newsgroup is a living example of the use of free
speech where amateurs can take on the guise of professionalism despite
their lowly education level.
