Default 20m FD Dipole

I've participated in Field Day every year since 1993, when I was first
licensed. Because I had a big 2m beam, I worked that band
aggressively, sometimes making the most QSOs. Unfortunately we lost
our hilltop FD site in 2009 and the 2m production "down low" was
disappointing in '09 and '10.

This year some youngsters want to work 2m, so I'm moving to HF, 20m
being the most promising, I think. With the help of EZNEC (evaluation
version), I modeled a promising 20m dipole at 30'. It's almost exactly
75 ohms resistive at the freqs I want to use and I'm going to feed it
with RG-6, 0.7 dB/100 feet. My radio has an internal tuner to match
the 75-ohm cable, if I need it.

I'll report the results.
