Fred,
I seem to recall a simular antenna made by 'MFJ' or 'Hygain',
maybe? No idea how 'well' it worked.

I'm having a hard time seeing the "minimal reactance" part of this
design. Looking at the plot of S11 it looks pretty much like any
other antenna with a single resonance.

It has "minimal" reactance at resonance and is highly reactive
elsewhere.
