7J4AAL in Japan is now sporting the largest Yagi currently in use on 160 meters – a full-size, 3-element monster atop a rotating 200-ft (60m) tower.
The previous Largest 160m Yagi was at OH8X but a winter storm put the tower and antennas on the ground in December 2013. The same tower also supported an 80m Yagi. I’ve worked OH8X a number of times in various contests but never on 80 or 160 meters and remember reading that their 160m Yagi failed significantly to meet their expectations.
All that money spent on a system that was often outperformed by a much less expensive 4-square.
Hopefully the new Yagi at 7J4AAL will deliver the goods. OH8X is at 65d N latitude and 7J4AAL is much further south at 34d North and therefore won’t be nearly as susceptible to auroral degradation as the Finnish station.
After looking at the installation pics, my little 160m inverted L makes me feel – well, maybe I’d better skip the analogies…
