To be safe, I'd suggest frequencies atleast 250KHz and above.
Anything below that and you're likely to _really_ feel the RF.
Anyone else tried it at < 250KHz?
However, I once tried an experiement holding onto a neon tube where the
coil arced to one of the wired ends, but I was only in contact with the
glass tube, not the metal bits...but I did feel the energy passing over
my hands....I think the frequency, from memory, was around 280Khz.
Well, my 2.5cents worth! ;-)
Catchya!
