I compehend from the original article that the 3-D animation is included simply because the 2-D drawing is not so visually clear. IOW there are not 2 antenna versions, just 2 drawing attempts (BTW, your 2-D representation is better than the visually-challenged author's 2-D attempt). Use the 2-D drawing for dimensional application & the 3-D for actual construction. The last paragraph of the text explains that the Modification (vs a normal Cubical Quad) is to the feed that permits 3dB gain when receiving circular-polarized signals, so that would explain why no reflector was included in this very simple project & why text instruction was given to trial various alignments of the antenna to the station direction. As to wire guage to use for the antenna proper, use any normal insulated hook-up wire not to exceed ordinary lampcord in size. A local RadioShack or Hardware store are sources for the wire & 300-ohm TV twin-lead.
