Now if he could make it work efficiently on all frequencies with 50 ohms
impedence and with no requirement for further matching or adjustment of any
sort, I would be impressed. :-)

Well then, let me take you at least half way to being impressed:

1) "The technology is completely scalable: Take the component values and
divide them by two, and you get twice the frequency; take all the
component values and multiply them by two, and you are at half the
frequency," said Vincent. "There are two poles in the antenna, and where
I place the poles in relation to one another-how much I bring the two
resonant frequencies together or spread them apart-enables me to emulate
different antennas, from a quarter-wave to a five-eighths wave."
"
2) "All I have to do is tap the helix at its base, and you get a perfect
50-ohm match with out any lossy networks as are required for other
advanced antenna designs," said Vincent.

3) "Eight years ago, antenna design was 90 percent black magic and 10
percent theory," said Vincent. "But now, with my design, they are 10
percent black magic and 90 percent theory."

He mentions being able to create these in 1/4 to 5/8 design--so, create
a 1/2 and loose the radials and salt water ...

It is difficult to find real detail on this antenna! Makes 'ya wonder,
don't it?
