Hi All,

You guys are giving me such good advice today, that I can't resist
another question.

I'm considering trying to phase a four element quad at 40 feet on one
tower with a four element 20 meter monoband yagi on another tower at 90
feet.  In order to do this, I need a variable delay line.  Is the best
way to do this using a set of coaxial delay lines whose lengths are
related to one another in a binary fashion, or are there other better
ways of doing this? 

73,

Rob, KL7NA
