I'd be interested to find out more details. That would be pretty
unusual, unless, perhaps the mesh wasn't hooked up to anything.
I'll try to find that webpage again for you.
Are you operating your coil outside? or indoors? If you're indoors,
running a long wire to the outside doesn't really help anything, and
could make things worse.
How big is the coil?
I'm building the coil on my 2' x 6' windowsill. Once all the components
are built and it's working right, I plan on incorporating it into a
portable table. I plan on keeping it indoors though.
