I went to your website but I didn't see any specific antenna
information,
like a ham might want to build a new type of antenna, to try it out.

A helix is an excellent example to talk about to arrive at small full
wave antennas.
When you follow the reasoning of the extension to Gaussian law of
statics which makes
it dynamic it brings to the surface that a radiator can be any size or
shape as long as it is in equilibrium.

By the way my antennas are always of a full wavelength which by virtue
of its reduced volume then becomes a small FULL wave antennas to
retain the inherrent efficiencies of full wave antennas in equilibrium
as well as resonant.
Allow me to continu on this line of thinking. It should now be seen
that an array is also shrunken not only by the shortened elements but
also by the fact that element spacings conform to the equilibrium of
the array as a whole! We then have an array that does not have to have
elements at certain distance from each other ad infirnitum but just
two elements much closer together where all radiation is accounted
for!
Hope the above helps you out.

Well, I'm good with the cheers and beers, but no way am I close
to clipping and snipping (wire) to make an Unwin Antenna.

What do they look like? Photos? Diagrams? Crayola drawings?

Don't get me wrong, OM, theory is important but there's no textbook
that loads up at 7220 KHz. Show me some metal parts.

Tell you what, get some wire twice the WL of the frequency you are
interested in.
Wind a close coil any diameter with it until half the wire is used
then change direction and come back
without changing wire winding direction and wind the wire on top of
the first coil where you finish with two wires to feed.
Put a variometer in series with it and then get on the air. Now this
is not exactly in equilibrium because one coil is a larger diameter
than
the other. Nor is the wire pre twisted pair which nullifies near field
noise to my thinking. Now you have a helix style antenna but without
the helix.
Coat the antenna with an alkyd type solution before you slide it off
the tube since the inside coil must be exposed the same way the
outside coil is exposed
'So it is easy to build a common standard form as stated on my page. I
really do not know what the beef is. Alternatively make a zig zag with
your wire two times and connect the wires at the top so you have two
laminations,. Be inventive and don't throw your other antenna away.
Hams in the past have tested their new antennas only to get insulted
over the manner of testing so a ham should never make claims regarding
gain
