A fact is a reality. An opinion lacking credible testimony is not a
proven fact.

Wave tilt is a known phenomenon. A wave traveling along the surface of
the earth is slightly slowed by the earth, so it seems to tilt slightly
in its direction of travel, like "dragging its feet".

A wave reflected by grazing a surface has an angle of reflection equal
to its angle of incidence. An incoming wave reflected by the ionosphere
has a tilt with respect to the horizontal.

A Beverage antenna can be as simple as a wire supported at low altitude
above the earth, and a seeming paradox is that although horizontal, the
wire is sensitive to vertically polarized waves. Despite Art`s
questioning that hams would know about wave tilt, an ARRL publication,
ON4UN`s "Low-Band DXing", begins its chapter on Special Receiving
Antennas with the Beverage.

Most engineers in this newsgroup are well aware of the facts needed in
their profession. One particular mechanical engineer is claiming new
discoveries without sufficient supporting information.

I understand that a diamagnetic field is oriented differently to the
norm
Thus a diamagnetic field on a radiator is different to the norm.
This I see as the lynch pin of radiation. Hams do not recognise what
science has found for some reason. There is not a physics based ham on
the group that will explain this type of field
and it was not known by Terman so the dark ages persist. Also I claim
no new discoveries. Every thing I have described is documented on
Google which you do not have the ability to check out....Tough.You
don't know how to use an antenna computor program so you can't see
tilt for your self. You are in sad shape.If you can point to anything
that I stated is NOT fact
then speak up with the details and share with the group
