The Mighty Big Array of Finn Jensen LA8YB stands as one of the world's largest amateur radio antenna systems. Built over 10 years in forests near Oslo, this 32 x 17-ele-Yagi array for 144 MHz represents extraordinary engineering dedication. The main horizontal mast spans two towers running on a rail circle, all designed and raised by Finn himself at an age when most retire.

With only 10 W of RF output power, Finn could hear his own echoes off the Moon and work single-Yagi stations in CW with ease. The array's massive scale is evident in feeder cables thicker than typical antenna masts. His achievement earned the WAS award, confirming contacts with all 52 US states on 144 MHz via Earth-Moon-Earth propagation.

Beyond technical prowess, Finn was remembered as an outstanding radio amateur—always helpful with a clever mind. He operated this EME station from a modest cottage deep in the forest. Finn Jensen LA8YB lost his battle with cancer and passed away on 20.8.2011, leaving behind a monumental legacy in amateur radio. LA8AJA documented additional photos of this remarkable installation on his website.
