Gee guys, I thot salt water was such an excellent ground plane that
nothing else was needed. I had very good luck, with the XYL making
worldwird contacts, using a Butternut multiband vertical and 2 radials
for each band but folk wisdom says we'd have done much better with a
better ground plane - like over salt water. So what's the problem with
simply throwing one random-cut "radial" over the fantail and/or
"grounding" the rig and tuner to a convenient brass thru-hull??
