Also read Gordon West's excellent primer on radio gound planes for
boats. It comes packed with the West Marine 2" copper foil gound kit,
which by the way comes in 25' AND 50' lengths. (That may say
something about the length of gound leads right there.) He points out
that the tuner is mounted next to the antenna on the flybridge of
power boats, and at the base of the antenna (backstay) of sailboats.
