Hello,

Does somebody have experience with ANSOF (www.antennasoftware.com.ar),
especially with planar circuits? Is this a NEC based package?

They say you can use a flat strip as basic element (like in the
"planar" commercial SW packages), though they speak of wire segments
in most other documents on their site. They also mention that you can
simulate wire segments in dielectric or magnetic media. This looks
nice for the relative low price.

Best regards,

Hello Wim...

I haven't use it, but I can steer you to where you can get your questions
answered.

Go to www.antennex.com , This site is devoted entirely to antennas and
related items. Join the antenna discussion list (no charge) and post your
question there.

If there is a group that is more aware of what is going on with antennas, I
haven't found it. Everything from PhD professors to ex and current
professional antenna designers to "just plain hams" (like me).

All the best

Ah, yes, the website that promoted the CFA while simultaneously warping
electromagnetic theory. But then I guess I just "don't understand".
Thanks, but I'll stick with ARRL pubs and ref books by Kraus, Jasik,
Terman, King & Harrison, et al for trusted, practical info on antennas.
73s,

then what are you doing in here, home of art, mr.b, and in past years,
fracky himself!

Because it's entertaining, often thought-provoking and never dull. I
have no quarrels with the folks you mention and they can hold whatever
views they wish; they are certainly capable of producing workable ham
band antennas. The problem is the "procrustean bed" that is often used
to "fit" the theory to the antenna design. In the extreme it's the
difference between tinkering and hoping for an efficient, practical
solution vs. applying good engineering and science in coming up with a
viable implementation (which is why I mentioned those reference books in
my previous post). Sincerely, and 73s from N4GGO,

Hello John,

OT: There is info on EH, CFA and other fancy antennas on antennex, and
many other places. That doesn't make such places useless. I have dug
through many documents on antennex and there is lot's of useful info.

As with all "information", the difficulty is finding out whether the
"information" is useful for one's special situation. Some of my
favourite books: Kraus, Orfanidis, the services textbook of radio
volume 5, antenna engineering handbook (Johnson).

Well, I was there for most of the CFA "saga," and saw no such "promotion."
Instead, I watched the constant stream of challenges by both Jack Stone --
the publisher, and a host of others (including yours truly) that examined
the CFA from all angles and came to the same conclusion: The CFA is/was a
hoax based on the inventors's lack of understanding of EM theory.

All the best,

Hello, and yes, IIRC to his credit Mr. Stone did publish (later on) Dr.
John Belrose's "mythbusting" of the CFA. Who at antennex was demanding
performance measurements to substantiate the CFA's proponents' claims?
Did the quantity and duration of those CFA articles on the website
confer legitimacy and promotion? Did Mr. Stone transform from believer
to skeptic? I wonder if antennex is at least in part more about
entertainment and tantalizing pseudo-science rather than reality. Like
a certain TV show starring two Roto-Rooter plumbers "ghost hunting" in
their spare(?) time. Hey, if you can't get valid measurements on your
test equipment just substitute melodramatics. 73s,
