In this case "shielded" is the wrong term. The spiral wire does not actually shield the noise, it prevents the noise from being transmitted. It acts as an inductor to prevent the propagation of the noise generated at the spark gap from propagating up the wire.

It has to do with the resistance of the long thin Monel wire. An impedance
mismatch and inductive reactance. What the mechanism is I do not know. That is
why Tracy is here, to explain such matters.

My last massage got a little garbled, the way I have my wires configured
now, the conductor and spiral wrap are exposed and folded under the crimped
teminal ends, so aren't both the conductor and the spiral wrap acting as a
conductor? What is doing the shielding?
