[TowerTalk] DIR-DE-DIR on a 40m yagi ?

[David Gilbert]

I'd have to run it through EZNEC to see what the best spacing is, but 
the "best" spacing may vary depending upon things like bandwidth versus 
gain.  I'll assume that you want maximum gain, but I won't be able to 
run it until later ... my wife just had surgery on the heel of her right 
foot and I'm playing Candy Striper.
