Not OWA's, but N6BT's "Array of Light" includes lots of designs for 
mono- and multi-band antennas, and also talks about interleaving and 
coupling methods. As you probably know, Tom's antennas are extremely 
good designs for their day (~ 20 years ago), and measured that way on 
the well-designed test range that K7LXC/N0AX devised. We've made great 
use of his smallest 2-el from that vintage, the C3SS, for FD and 7QP/CQP 
county expeditions. W6GJB rebuilt them to allow the elements to be 
transported fully put together on a rack above his contesting trailer 
and clamp onto the boom, thus allowing very fast setup. k9yc.com/7QP.pdf 
for photos.
