A "flattened" coil, first time I see one used is Vincents' DLM, anyone?

Looks like linear loading to me.

All joking aside, the point is, a helical/circular coil is not a magical
arrangement ... but then, you already knew that.

I have constructed shortened antennas using pvc pipe with sets of
parallel holes drilled on each side and the conductor "laced" through
the pipe and forming "loops" on each side of the antenna--if nothing
else, the visual of them provoked responses ... I now use such an
arrangement on the bottom helical of my Vincent 20m (modified gamma.)
