Hello, Steve, and all. *Steve, I see you also have an informative

Yes, that article described the process by which I arrived at the
broadband version.

Since then there have been a couple of write-ups in the monthly
Antenna column of RadioCommunication magazine, and RSGB published the
design in their recent book "Building successful HF antennas". You may
also have seen Leo's (K4KIO) constructional article in the March
edition of QST. All that has generated quite a lot of interest in the
antenna.

I try to avoid exagerated claims for the design - at the end of the
day it's a "compressed" Yagi and performs as such. But it does provide
useful directivity over the five bands 20m thru 10m, with a single
feedline, in a size which suits those of us that don't have a lot of
space. It's also pretty easy to construct from readily-available
materials, although a number of folk now supply complete kits,
including K4KIO and more recently DX Engineering.

Thanks for the reply, Steve. As for exaggerated claims, I'd have to
give the award to the designers of (and explainers of the "theory"
behind) the Crossed-Field Antenna (CFA). (Of course the CFA has been
the subject of numerous antenneX articles but I'm not placing yours in
that group!) 73s,

I guess that you haven't seen info provided by Art on his shoe-box
sized 160M thru whatever antenna that has +9 db gain, and a pencil-thin beam
of radiated particles. Art's technical expertise beats the crap out of the
CFA
guys, as HE (Art) improves on Maxwell's and Gauss' equations, too. And all
of this from a retired mechanical engineer, working in his backyard!

Here's my candidate for the award, embodied in a U.S. patent:

This particular antenna has the useful property of enhancing plant
growth too..

It has been observed by the inventor and witnesses that accelerated
plant growth can occur using the present invention.

I think David Strom knew what we was writing about. He deserves a beer.
