And, any decent modeling code(s) will have extensive validation against
range tests, so it's not much of a surprise when the antenna works as
modeled. The surprises come from aspects that weren't modeled.

Jim:

Your text is interesting.

I went ahead and put together, on the little I could glean from the info
on this, an antenna. I marked a pvc pipe on both sides, drilled it, and
put the wire though, basically as a series of hair pin loops. "Tap'ed"
it, obtained a 50 ohm match (had to use a variable cap) and it works, I
need more data ...

I need a complete pic and data so I can duplicate his construction ... I
have an open mind. However, this "thing" is so simple, it is better I
confirm or reject "it" on my own observations ... it may, or may not, be
nothing ...
