In 2006, the contest's position was put into operation a new antenna system on the range of 20 meters, mounted on freestanding tower height of 82 meters. Four 7-element antennas "Yagi" in the range of 20 meters can be remotely controlled to operate as a stack with a focus on the U.S., as well as individually. The upper antenna stack rotating. Previously been used in this direction stack antennas "Yagi" (3x6 elements) was redirected to Japan, which enabled the simultaneous work effectively stacks of antennas on the two most preferred direction - "US-Japan" and, if necessary, by rotating the upper antenna stacks work in one or two additional directions, depending on the specific conditions of competition and radio propagation conditions. Third, the rotating three-element antenna "Yagi", allows (in some cases) with a large work more efficiently with reporters in the nearby areas of communication.
