Manual for the Finco A-62 combination 6 and 2 meter yagi. Compliments of Kerry Steffens, W0ON.
Just a note on the FINCO 6&2 antenna. The manual neglects to mention that the hairpin (Beta) match slopes downward away from the boom. Also the antenna is tuned on 6 meter by the gamma match which is intuitive. What is not obvious is that the patristic stub 300 ohm match is tuned by bending the 10 AWG portion toward the 6 meter driven element. It is reasonably flat across the band, but you can tweak the 2 meter phone calling frequency a bit lower to almost a 1:1 match. Also the matching insulator needs to be shimmed to remove the air gap so that when it is tighten down the insulator doesn't split. Like all antennas, a good reading on the ground still may need tweaking on the tower. 73s Kerry W0ON
