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
