The preceding confusion not withstanding, surely you must have aligned
antenna elements to vertical or horizontal positions to maximize signal.
I`ve done so countless times while optimizing microwave paths.
The difference is extremely small similar to who wins a 100 metre race
but there is still
one winner
Terman quantifies (look it up for the math, Art) signal degradation
caused by misalignment on page 923 of his 1955 opus. I`ll extract one
sentence:
"It will be observed that the quantity
(E cos psi cos theta) is the component of the field strength which has a
wavefront parallel to the antenna and is polarized in the same plane as
the antenna."
Yes they do!
Terman does not include the eddy currents vector where computer
programs based on Gauss and Maxwell and other masters do.
The angle of difference is similar to that seen as the pitch angle of
a helix antenna.
With your love of Terman you can now state that computor programs are
garbage
since they promote what you call a "myth"
The programs Art refers to don`t contradict either Maxwell or Terman.
As I said earlier, yes they do with respect to Terman.
I challenge you to find in Terman the implications of Foucault current
with respect to antennas
and diamagnetic materials such as aluminum gold and copper which are
prime examples of material with suitable resistivity values
that provide ejection or levitation effects when moved thru a magnetic
field
It is nothing new, The vector has been there all the time it is just
that many don;'t mess with it because it is small and a devil to
calculate.
Richard why not give it up? You will never make the antenna, you can't
operate computor programs and I suspect you cannot perform a google
search, so progress beyond Terman is an impossibility for you. If
eddy currents are omitted any structure thus made cannot be in
equilibrium since this is the mystery "weak" force that Einstein
struggled for in vain and thus drove him towards forming quantum
mechanics., The masters made room for this force even tho they did not
know what caused it but that vector was required to conform with
equilibrium closed vector field
