Building a Hen-tenna for 2 meters.
If you want a compact, simple 2 meter antenna that exhibits a low angle of radiation and almost 3db of gain broadside, then the "Hen-tenna" is for you. Radio amateurs have modified this Japanese-inspired antenna to include HF, 144 MHz, and 70 cm coverage. Paul (VK3HN) does an excellent job of taking us through the design, building, and testing phases of this basic 2 meter SSB antenna.

Here are some comments from Paul (VK3HNN)" Hen-tenna is a rectangular loop antenna (of Japanese origin) that hangs vertically but, surprisingly, is horizontally polarised. It is simple, compact and offers over 3dBd gain broadside. It is quite broad in its resonance, mine was under 1.3:1 from 144 to 146MHz. This video shows a version being made for 2m SSB, and a field test. Hentenna calculator: https://www.la2pj.net/software/henten... My blog: http
