Not enough power, probably.

However, the conductivity of the salt water would make the Efield
magnitude very small (in a V/cm sense), probably so small the neon won't
ionize.

Indeed, I suspect this is the case.

Try small fibers in distilled water or oil as a start.

Oddly, ice is a pretty good insulator, and also doesn't absorb RF well,
which is why defrosting in a microwave is a tricky business. The
absorbtion rises dramatically in the thawed meat, relative to the frozen
(which doesn't absorb much at all). This is why that frozen chicken has
cooked parts and frozen parts simultaneously when thawed. (The defrost
setting on the microwave is pulsed not to reduce the average power, but
to give time for the heat in the already thawed parts to move to the
frozen parts.)

Oh, you mean that standing in the tub of salt water holding a metal rod
isn't a good idea? I figured that they could examine my internal body
structure at the autopsy, and thereby gain more information for coilers
everywhere....
