G7FEK’s original “Nested Marconi Antenna” was first designed in 1988 and comprised two quarter-waves in parallel, fed against ground in inverted L. The original antenna was roughly 50 feet long x 22 feet high. During 2007 the antenna was optimised and tested at sunspot minimum to improve performance and multi-band operation. 50 years ago today they tried to silence pirate radio for good.Ham radio PDF repository curated by N5DUX.
