Default Whip antennas with coils

A long time ago there was a arguement both on this group and on E ham
with respect to the function of a coil with respect to replacing
missing degrees of a wavelength.
Both Tom W8ji and Roy W7EL did experiments which apparently justified
an account written up by Tom under the subject.
You should look it up and read it.
Tom states that the double helix is totally resistive and antenna
elements should be straight reffering to spacial distance.,
He then came to the astonishing conclusion that for maximum efficiency
radiators should be straight and for some reason dismissed the double
helix to give strength to his claim that radiators must be straight
which is fraudulent. A straight radiator generates a external magnetic
field which introduces losses whereas the double helix supplies all
applied current to the generation of radiation. None of the experts on
either group challenged challenged the statement allegedly supported
by both Tom and Roy
and it still remains in print to this day

I continued on reading Toms many dissertations on radiation and
antennas when I came across a lecture he gave at Dayton regarding
small antennas. Again he pushed his personal intuition with respect to
small antennas and spacial distance
and received no rebuttals from the audience or the ARRL . In addition
he always spouts his pet sentence on radiation is by the acceleration
of charge but never states what the charge carrier is
as he is still wedded to the idea of wave carriers which has no
justification what so ever. We desperately need the help from physics
majors to challenge the spread of old wives tales that are propagated
without technical justification and sucked in by the new generation of
which the hobby is now created or we lose the credibility obtained by
hams who foraged before us with respect to the state of the art.

its all up to you art, i suggest you write the definitive expose on
antenna myths... it should find a good spot in the humor section of
the book stores.
