Maybe - or maybe not.

Fact is that without more info we're not in a position to judge the
thing one way or another. Maybe it's a breakthrough, maybe it's one of
things that is great in theory but totally impractical, or maybe it's
a dud. Without more info, any judgement is just raw speculation. And
since a patent application is involved we're not going to see much
real data for a while anyway.

One point to watch for, though: What matters in practical antennas is
the performance of the entire antenna system, not just the antenna
itself. For example, a short (in terms of wavelength) whip antenna can
be quite efficient - it's the matching network and ground system
losses that reduce antenna system efficiency, and bandwidth, to low
numbers.

Hello, Jim

Your point about matching network and ground losses is well taken.

We keep hoping for that "perfect" antenna. An IEEE publication back in 1995
pointed out that the Northern Lights are caused by ions that are far too
small to be efficient radiators of light - and yet they radiate light. In
theory, an antenna can be vanishingly small and yet be efficient - and even
possess gain!

If any one has a 6 inch whip with a 3 dBi gain on 75 meters, let me know.
I'd like to try it first, however. Don't ask for money up front like all of
the notes I receive about transferring $10,000,000.00 US for which I receive
$1,000,000.00 - uh, but have to send someone some up front cash to ensure
the account is good )
