Build your mobile antenna which outperforms Hustler by 10db and ATAS-100 by 18db. From 80 to 10m. The HB9ABX mobile HF antenna, designed for 10 to 80 meters, was developed by Felix Meyer and outperforms commercial antennas like HUSTLER and YAESU ATAS-100/120 in field tests. Made from fiberglass rods and enamelled copper wire, it includes a loading coil with adjustable taps for tuning across bands. Installation requires solid grounding, and adjustments are made via whip length and coil settings. An antenna tuner ensures optimal SWR. Users must handle fiberglass with care due to health risks. This design proved highly effective in South America and Europe. -
