[AMRadio] HV Wire

I don't have personal experience (and don't want any), but have heard horror
stories regarding the use of coaxial cable as high voltage wire.

Short answer: Don't do it!

Use fresh cable designed for the purpose.  If you are willing to experiment
with a potentially lethal configuration, at least route the wire away from
any exposed surfaces.   If it does let go at least it won't be through you.

What is this ref to "foam" all about?

If RG-8 is good to 40 kv, one would think RG-58 would be adequate for a
few KV, no?  And a lot easier to work with.
