...I am looking for the construction article "FRACTAL Antenna for 10m" that
appeared sometime ago in I think either QST, Ham Radio, or 73 magazines.
I have a lot of spare time on my hands - so I thought I would like to
construct one and use it portable as I live in a Antenna Restricted
Community.

As others have mentioned, several articles appeared in various magazines

Obviously you will need two mirror image windings to create a dipole
antenna,
Mike,
the definition I arrived at is that as long as the wire represents one
wave length,
is resonant and in equilibrium while at the same time holding to the L/
C ratio of the material in question.
This can be produced with just two degrees of freedom by folding
the wire at the half wave point
and then wind the two wires in pancake shape/form.
You can also wind two in series where capacitive actions
between them can create a variety of results.
The important point is that one must hold to the
conditions set in the definition
(no exceptions)
Art
ideally as closely matched in dimensions as possible. Efficiencies
can approach 50% of a full sized radiating element.
Hope this helps
