I am intrigued by this design and thinking of building one. It looks like one for 30 meters is about 33’ by 12’. For 20, 24’ x 9’. 40 meters would be a little too large, 48’ x 19’. I am interested in hearing from anybody who has one, built one or thinking about one. What kind of materials were used, for example. I have a QST article about the Black Widow beam built for 15 meters with crappie poles used for supports. I am especially interested in its feasibility for QRP operation on my deck or in a park.
