At the frequencies we are using most of the current flowing through
the primary windings should be in the outer most layer of the
conductors (skin effect). Has anyone compared the performance of a
copper tubing primary to a silver plated copper tubing primary. It
would require a heavy silver plating to insure that all conduction
was going through the silver and not the copper. In theory if all of
our primary currents are traveling only through the outer few mills
of the conductors we may be able to use silver plated plastic tubing
(maybe garden hose for really large coils) for inexpensive primaries
that may very well yield better efficiency's than copper tubing and
be a heck of a lot easier to work as well! BTW does anyone know of
any equation to calculate the depth of conduction for a given
frequency, I vaguely remember seeing a formula for calculating the
depth of skin effect for a given frequency. This would expedite the
determination of what thickness the plating should be.
Sincerely
