An update from a post of March, 2018
Forty meters: Following a QST article from July, 1972, The W2FMI 20-Meter Vertical Beam, we scaled to 40 meters. This is a three element yagi made of three quarter-wave verticals. Gain is less than a dipole but better than a single vertical. It will be aimed toward Europe.
The pattern was very narrow right through central Europe, like a knife edge.
Three days after completion a wind storm blew down both the director and the reflector. The driven element survived and was used for a time as a quarter wave vertical. Life happens. Inspired by the performance of this antenna, a 160 meter version was completed in 2021. A possibility also exists of resurrecting the 40 meter yagi. A 30 foot tower with a tri-band beam now resides on the site. Perfect for an omega match tuned to 40 meters. The old director and reflector are still around and could be re-installed. Radials were relocated so they would have to be re-installed. Capacitors for the omega match are in the junk box. If the weather stays nice this fall, this might be a good late fall project. DXCC is already accomplished on 40 but the DXCC Challenge always needs new QSO’s.
