So it sounds to me like the bottom 1/4 wave of the main radiating element is radiating out of phase and being captured by the in-phase radiation of the radial cone, thus providing another additional 1/4 wave in-phase element in a relative collinear fashion, plus acting as a feed system for the upper 1/2 - 5/8 wave part of the antenna, but doing so in a manner which lowers the TOA below that of a single 1/2 - 5/8 antenna.

If this is close to being anywhere near accurate it seems the next logical step would be a full wave main radiating element with a 1/2 wavelength radial cone to extract the gain & flat - downward TOA equivalent of a 1/2wl above a 1/2wl collinear.
