Consider: a commercial AM quarterwave, vertical antenna is probably
95% to 99% efficient. To have an incredible efficiency would add only
4% more to a very simple design that has been around for 100 years.

+0.2dB or less is not incredible efficiency.

You cannot hear 0.2dB difference in sound, you cannot measure 0.2dB RF
difference except with great difficulty.

Thanks for reply, Richard.
Take also into account that, although i don't know much mathematic, i don't
have any doubt that is impossible that this kind of antenna can have a great
or also medium efficiency.

Considering your 1/4 wave AM broadcast antenna example, is not an accident
that nor military nor broadcast installations used in the past a type of
antenna like the EH/HZ...
.... and military brains have knowledges that we in the "civilian" world can
use maybe after 20-30 years.

And, if this really works, one don't waste time writing PDF. He start
working in radio with this antenna, and if the antenna is *really* what he
claim, he will be in a very short time a rich man.
