[TowerTalk] Dual Band OWA Design

[Jeff Blaine]

John, I built a 30/17 dual monoband using AutoEZ for the optimization.  
The result has been excellent and AutoEZ makes the various 
compromise/optimization considerations manageable.  If you enjoy that 
sort of work, using this project to gain competence with AUtoEZ will be 
very rewarding.
