Ed,

If I remember correctly mine were only 10'-12'long. Probably just the
right length...

Brian,

I use RG-213 coax as feed lines from my distribution transformer to the
coil, about 20 feet.  I originally had the shield grounded and did not
experience this problem.  I did eventually remove the outer jacket and
shield after reading about other coilers problems with this.  There must
be
a particular set of conditions that cause a 60 hz resonance for some set
up
and not others.
