Could anyone direct me to any references on the web or on hard copy that
discuss the theory behind the Force 12 C-3 antenna designs? In particular
how the 20m driven element "feeds" the other driven elements, and how the
antenna winds up being "resonant" on 18 and 24 Mhz even though it wasn't
particularly designed for that (I've even heard they'll tune on 6m). I've
read the short article on "Open Sleeve Antennas" from the ARRL Antenna Book,
but I'd like to learn some more.
Thanks to all
