RE: [TCML] JavaTc specs for my new resonator
Sorry I am a little behind on my reading - but I built a 48" tube toriod from 3/4" hardline coax. It consisted of 7 rings. I found that JAVATC is fairly accurate vs measured resonance if the toriod is modeled as seven toroids with a minor diameter the same as used in construction.
