Walt, I intended to include a link to your article and looked on your
web site for it before I posted my article. But I didn't find it in the
index. Where is it relative to your home page? I'll add a link to it.

Walt's article was really the first one I ever saw that explained the
phenomenon of currents on the inside and outside of the coax -- my
article is really just an extension of his work.

Yes, Roy's article in the Compendium is excellent, as are all of Roy's
contributions to our art. In his article he referenced my work with
baluns, which appeared in QST for March 1983. This article is also
available on my web page at www.w2du.com for those who don't have a
copy of that issue of QST.

Roy,
Although no credit is given or author claimed, the Radio Works Product
Manual includes a similar drawing and detailed explanation of same. This has
been in print every year for at least the 6 years that I have been buying
products from them. It is the basis for their design, production and
marketing of the current-type baluns. Radio Works also recommends a line
isolator at the transmitter-end, due to near field coupling of antenna
currents onto the coax shield that a Balun cannot prevent. I have never used
that product but it is popular.

Roy, I changed the address to my web page on 3-13-05 to the one listed
above. I also changed the format somewhat.for better organization. The
new page lists the pertinent categories with links to the individual
chapters from Reflections and its appendices. You'll find the chapter
on baluns under the category "Read Chapters from Reflections 2," with
the title, "Some Aspects of the Balun Problem," Chapter 21 in the
book. Thanks for the assist.

I forgor to mention that I recently wrote an addition to Chapter 21,
Chapter 21A for Reflections 3, telling what led to the development of
the W2DU balun. It also appears on my web page under the category
"Preview Chapters from Reflections 3," The idea came while fixing a
problem that arose in measuring the radiation patterns of antennas I
developed for use on various spacecraft at the antenna lab of the RCA
Space Center, Princeton, NJ in the 1970s
