Default Induced signal?

I modeled the original question Cecil asked on r.r.a.a. (current on a
coax center conductor of a monopole made of coax) because I was curious
and because my wetware simulation for the amount of RF coupled into the
end of a piece of coaxial cable wasn't up to the task. I didn't start
with the eHam question in mind.

I don't know offhand how much the coupling between the center conductor
and shield is at the ends of the coax, so I tried some stuff with the
only electromagnetic code I have lying around my house.

The relay question is not very interesting, it's just an engineering
one.. throw good chokes at it. Done. I agree.

I wanted to know what the current was in the center conductor of a
piece of RG-8 being used as a monopole. The answer to that question is
not trivially calculable, though it might be trivial in the sense of
being trivia... who cares? I did.
