If Kraus said "The radiation is perpendicular to the accelleration"

Balanis says, speaking of an infinitesimal dipole:
"Integrating the complex Poynting vector over a closed
sphere, ... results in the power (real and imaginary)
directed in the radial direction. Any transverse
components of power density, ... will not be captured by
the integration even though they are part of the overall
power."

Apparently, Kraus' assertion is a result of the integration
math and does not necessarily correspond to reality.

Another point to reckon with is the tilted folded dipole
The experiment the Naval departgment under took when comparing
antennas.
The results showed that antennas tipped away from parallelism to the
ground
provided best results for their use which concentrated on receiving.
All existing antennas were removed and replaced by tilted radiators.
Thus their tests showed that tipped radiators was not a "myth" as
stated by this group
and also radiationis not primarily at right angles to a radiator.Is
the Navy at fault by not conforming
to Kraus's and other expert teachings and aligning themselves to
facts attained in the field.
As Reagan stated "Trust but verify" The same goes for students who
suck up what the experts
and professors state without verifying from first principles. Choice
of answers will
allow memorisation to pass the exam but not to arrive at the cusp of
new discoveries!
