Abstract
The article informs on an updated version of Koji Sugihara's, JJ1UMS, 1982 6-meter "Hentenna," the Hen-Delta improves performance and is easy to build and tune. It mentions top of the Hen-Delta is wider than the bottom, which pushes the effective center of radiation upward, and maximum radiation moves upward because of the proximity of the out- of-phase and equal-amplitude currents in the Hen-Delta's lower conductors, thus canceling radiation from the vertical antenna section.
