Thanks for this info, Lou. I think I'm more concerned with needing tables for
figuring phase/angle relationships etc for tan etc.
I got a set of tapes from Handi-Hams for study. They're the ARRL Extra manual.
Being an audiologist I have the dB stuff down pretty well. Its the geometry and
trig that are eating my lunch <g>.
