Even more important than the obvious operational BS (where he
contradicts himself time and time again) is basic physics. EM
radiation does NOT come from magnetic or electric induction fields.
Radiation and induction fields are totally different physical
effects.
It all goes back to the spatial ampere-feet in an antenna, nothing
else. 5 feet of wire or 500 feet or wire in a five-foot space is a
five-foot antenna. Efficiency heavily depends on cancelling reactance
without adding unnecessary loss, and the EH antenna does a poor job
of that...and a good job of exciting the feedline.
By the way, the same guy who claims to have invented the E-H antenna
told a local radio club he invented the small loop antenna. Based on
that, he must be at least 130 years old.........so his obvious
technical mistakes are forgivable.73, Tom W8JI
