Figure on 30pF of capacitance per foot for coax. It will seriously
reduce AC voltage although with DC you'll get even more spark. i know,
having been bitten by 3' of disconnected coax that had been charged to
40KV.
You could try TV twin-lead.

if you run two pieces of coax - maybe RG 58? you will get less capacitive
loss but still get the good insulation - alternatively buy a roll of solid
core ignition wire.

I'm quite sure that stun guns deliver AC, not DC. Frequency would be
in the tens of KHz, nowhere near high enough for skin effect to
operate like it does with TIG HF.
They very probably operate at or quite near the self-resonant
frequency of the secondary, so loading the sec with any significant
capacitance will reduce frequency and peak voltage significantly.

>Coax?
I have a feeling coax is the worst wire to use. IIRC, coax tends to dampen
lightning strikes if my ARRL reading is remembered correctly.

Thanks. I'd never thought of that, and that would give a stiff durable
conductor that would be easy to make work..
