Thanks,Tim. I should have mentioned that my
secondary is 4 inches in diameter. So you're
doing a little over double your secondary
diameter. You get no arcs to the secondary? Do
you mind telling me how your primary is made? I
was thinking of just doing some turns on a
section of sonotube... Regards,Dan K From:

Diameter I don't know of a rule of thumb. But
I can say that my bipolar has a 8" diameter
primary with a 3 1/2" dia. secondary. Hope
this helps. Tim On Wed, Dec 5, 2018 at 7:41 PM
