[Elecraft] K3 on a boat

[Don Berger]

the efficacy of a counterpoise on boats has been the subject of much study
over the years during which many myths have been disproven. Among them is
the need for connection to a grounding plate which is good for dissipating
lightning but makes a poor counterpoise.

Another myth is that length of material underwater is of any importance. Or
that radials in the bilge is effective. Long story short - a so.id
connection to any thruhull is equally effective. I know because I’ve tried
all the options over many years.
