Art is trying to convince us that EM energy is also a mechanical force,
consisting of particles that fly off the end of our antennas like
little turds. The ramifications of that means that everything we
thought we know about RF - and in fact all physics is completely wrong.

You have made a small mistake. Antennas are feed with the oscillating
voltage. So the little truds fly off and come back. It is normal
longitudinal wave.
The key problem is what radiate: the end of an antenna or something
else.
What do you think?
S*

No, you've made a mistake ... again. *EM waves are transverse waves in
air (i.e. around a normal antenna) not longitudinal waves (see
http://en.wikipedia.org/wiki/Longitudinal_wave).

EM waves by Maxwell are transverse waves. They are the paper waves. The
real electric waves are mainly longitudinal.

* Would you care to cite a reference where it is stated that EM waves in the
far field of a transmitting antenna contain a significant longitudinal
component? *Many respected authors, such as Kraus, have illustrated the
contrary, but their work isn't limited to paper; people like Kraus have
designed real antennas of types that are still in use today.

Sound waves are longitudinal because air pressure is a scalar, whereas
electric and magnetic fields are vectors - they have polarisation.

The math has not to do here.

* What 'math'? ... just the mention of scalars and vectors, in a group
devoted to antennas. *Please.

Here is the full acoustic analogy. The two loudspeakers work like the two
monopoles.

* Rubbish. *What 'two loudspeakers'? *Ever heard of a horn loudspeaker? ...
it produces longitudinal pressure waves.

Also, antennas that radiate are fed with alternating current. *The
terminal voltage is almost immaterial in comparison with the current -
that's what causes the radiation.

If you want to discover what radiates I suggest you read one of the
normal text books on the subject, like Kraus 'Antennas', and stop making
up your own versions!

To discower what radiates will be better to do experiments with tipping of
monopole antenas.

* Where do you get this stuff from? *Please visit a library - you could do
yourself a lot of good.

Chris, what I believe he is referring to is that computer programs
support a tipped vertical over one at right angles to earth. Computer
programs are supposed to be based on Maxwell's formula. Is this an
error and how do we fix it. If it is not an error then it supports the
presence of the Coriolis force in collusion with gravity. and not
gravity alone.
More to the point, it is common knoweledge that there is no full
understanding of radiation
available anywhere. Thus he is asking probing questions to fill in the
gaps.
Personaly I am not willing yet to say antenna programs are at fault
until more explanations come about. Can you explain what he is
commenting upon.?
