Why do you persist in posting and defending your unproven and zany beliefs
about equilibrium, particles etc that you suggest apply to your "Unwin"
antenna, if you don't even know how the free-space radiation envelope from
your Unwin antenna compares to that of a proven reference radiator, for a
given applied power?

The RADIATION performance of a transmit antenna should be considered before
everything else. Even a 1:1 SWR at the "antenna" input terminals over an
infinite bandwidth means ~nothing if very little to none of the r-f power
applied there is radiated in the form of an EM wave.

Why should any serious investigator be interested in reading about how you
think your Unwin antenna operates, if you can't *first* evaluate, publish,
and scientifically defend its free space radiation characteristics as
compared to a known standard radiator, such as that of a resonant,
center-fed, 1/2-wave dipole?

Yup, it is difficult, But I trust my logic in the face of contrary
statements that have no logic.
How can anybody supply a theory based solely on mathematic
tumbles....... but they do.
How can people who oil tractors and the like on road building and
nothing else and
call themselves engineers,...but they do. Some engineers put a wig on
their heads
and from then call themselves judges........but they do! Some
people unlock the doors
of a radio station every morning and call themselves broardcast
engineers no less
...............but they do!

And that's fine. But what about trusting your logic in the face of
contrary statements that do have logic? That's not so fine, is it?

You've heard that old expression, "Put up or shut up."? Now's the
time.

And with that, this 'midwife' self-promoted to 'doctor' will retire
gracefully from this nonsense.

fortune in the fertilizer 'bid-nez'!)

Goof for you

Yes. John D. Kraus, the inventor of the helical antenna, did just that.
In his 1950 edition of "Antennas" on page 176 Kraus wrote:
"The term "transmission mode" is used to describe the manner in which an
electromagnetic wave is propagated along an infinite helix as though the
helix constituted an infinite transmission line or wave guide. A variety
of different transmission modes is possible,

The term "radiation mode" is used to describe the general form of the
far-field pattern of a finite helix. Although an infinite variety of
patterns is possible, two kinds are of particular interest. One is the
axial or beam mode of radiation (R1 mode), and the other is the normal
mode of radiation (Ro mode).
