it's a SPW that gets you 1.7 dbi gain.... as opposed to 1 dbi for the standard SPW.

RCExplorer used my original tutorial which is optimized for circularity. The OMM version has greater gain. The difference is the arc length and gap at the feed. My SPW build uses a 105 degree arc and minimal feedpoint gap. OMM's version uses a 90 degree arc and ~.05 wavelength feedpoint gap.
