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. "Sal" KD6VKW ("Vicious Killer Weasel") |
