This folding creates capacitive coupling at the ends of the elements. This coupling allows the antenna to achieve resonance in a significantly shorter physical length than a straight dipole.
The reason is a high-volume search is that the antenna requires precise dimensions. Unlike a dipole ("cut it long and trim"), a Moxon requires exact spacing and wire lengths to achieve that hot F/B ratio. hf antennas for all locations moxon pdf hot
If SWR is high at resonance, your feedpoint impedance is too high (100-120 ohms). Add a 50-ohm hairpin match. This folding creates capacitive coupling at the ends
