InnovAntennas 1712DUO 4-Element Yagi
InnovAntenna 1712DUO 4-Element Yagi is one of the latest designs from G0KSC. This very compact directional antenna for the 17 and 12m WARC bands (18 and 24 MHz) has no reflectors. One director per band and an LFA/dipole hybrid driver lies flat on its short, 5.1 ft. (1.56m) boom. This dual-band version has a second active element intentionally positioned for open-sleeve coupling with the hybrid driver. Consequently, this antenna requires only one feedline, avoiding potential interference and tuning issues caused by multiple feedlines.
This short boom directional antenna design is a smart choice for the WARC bands. Since SWR bandwidth is not a requirement, optimization for excellent gain and good F/B on a short boom length is reached. This dual-band Yagi for 17 and 12m was calculated using advanced software and perfected by hand. Designer Justin, G0KSC, has achieved particularly good electrical properties and robustness to provide reliable performance, even in adverse weather conditions.
