Should there be any difference in this respect between saltwater and a string of carbon? As I see it, the major objection to any probe that has to reference the top of the coil to ground is that it occupies physical space and modifies the permittivity and/or permeability of the medium it lives in. I think I will perform a cursory examination of the effects of a probe running through the centre of a resonator of a reasonably large diameter. It is not for nothing that an authoritative technique appears not to exist. Regards, Malcolm
