I've never claimed credit for the four square antenna, and no one makes
claims on my behalf. If anyone, friend or not, is claiming that I am the
originator of the four square antenna, he is in error. As often the
case, I have no idea where Art got his information, but if he will give
the name of this individual and where the alleged misinformation
appears, I'll contact him and tell him the true story of the origin of
the four square, which is as follows.

To my knowledge, its first creator was Dana Atchley, W1CF (now SK), in
association with others. He was certainly the first to give it that
name. Its introduction to the amateur community was "360 degree -
Steerable Vertical Phased Arrays", by Dana W. Atchley, Jr., W1CF, Harold
E. Stinehelfer, ex-W2ZRS, and Joseph F. White, PhD, in April 1976 _QST_.
Certain aspects of the antenna were patented in U.S. Patent 4,123,759
(Hines et al), but no restriction was ever imposed or enforced on the
use of the patented material to my knowledge. The article and patent
promoted the use of Wilkinson power dividers to supply power to the
elements, a method I knew which wouldn't produce the claimed results.
This resulted in my writing a long paper on phased array theory which I
sent to anyone who requested it at for the cost of duplication and
postage. Dana got one of these, and saw the error of using the Wilkinson
feed. The paper ended up being published as a major part of Chapter 8 of
the _ARRL Antenna Book_, where it's been for many years. You'll find the
_QST_ article by Atchley et al referenced at the end of the chapter.

Anyone who has EZNEC, including the demo, of version 3.0 or later (when
the Antenna Notes feature was added), is invited to open the 4square.ez
example file furnished with the program. Once opened, click File, then
Edit Antenna Notes. This will open the Antenna Notes file for the 4
square example antenna. The first sentence is "This popular phased array
was invented by Dany Atchley, W1CF."

Looked up an article on google called Four square antenna experiences
and to my amazement I found that one of Roy's close friends had
claimed
on his behalf that the four square antenna can be attributed to him.
I waited a while for what Roy had to say because certainly was an
achievement,
if true. Roy did not deny or enlargen on the achievement so I started
to dig for myself.
The above article was the first I came across and it precedes Roys
article in the antenna compendium by some thirty years. As expected
Roy still remains silent taking things on the chin in his normal shy
way.How many other things did he invent before the government released
antenna computor programs to the public and yet still stayed quiet? Is
there still a chance for a Nobel prize for other achievements not
declared?.
