This article describes the construction of a Moxon rectangle antenna for the 70MHz (4-meter) amateur radio band. This compact two-element beam design features folded element ends, reducing its width to approximately 75% of a half-wavelength. The antenna was built using enamelled copper wire stretched over a lightweight fiberglass kite spar frame, with a direct coaxial cable feed connection. Initial testing showed a VSWR of around 1.3 with distinct nulls at 90 degrees when horizontally mounted. The author later tested vertical polarization and suggested that the antenna's compact size might allow for indoor loft installation. -
