I'm still trying to wrap my mind around the antenna, I'm nowhere near
ready to model it. So as to not make any ignorant mistakes, the antenna
is counter-wound inductors, correct? and they are concurrently wound, as
in they sort of weave against each other? And this is a full wave
antenna? Do you use enameled wire, or what is the insulation? I'm
assuming that this might be important in regards to VF.

I think you should forget the whole idea. We have another expert
on line that can voutch for the fact that it is just a dummy load.
He joins the majority and I am only one,.....who actually has one no
less.!


What up Art? I'm trying to find out what the idea is behind this
antenna, not disrespect it.

I have use std house wiring,enamelled magnet wire and simple buried
dog wire.
which I believe has the lowest insulation. Min wire I have used is #22
because the wire is not meant to support anything so 100%
of fused value seems to be o.k.
I have taken the windings off of the former but it is lacking in
strength.
I am using a wood lathe so that I can wind at 90 overlap of the wire
which will leave small holes
and will be stronger.
I made a machine to do this in the U.k. before I came over which had
no holes and was made of glass fibre tape.
I sold the machine which I used for lampshades before I came ove.
Prior to that shades were of monofiliament wound in single direction.
The machine was really for making an equivalent fuel containers on
the Atlas rocket so I made one for myself out of bycycle chain and
infra red heaters and mad some pocket money.
All of these I have tuned up with 100 watts


Why not just wind a mirror image on your wlky talky antenna:
That way you are not using your body as a heat sink!s
