I agree with Alexander, 10kV is not so high. If you were looking
at > 30kV or 40kV or so, then it might become an issue. But even
then it can be controlled at the ends.
I think it just has to be tried and the practical limits found.
It is good to consider these things as the territory is unfamiliar.
Stefan, how will you feed power into the coil? I am running some
circuit models to see the effect of harmonics and coil overtones.
I want to see how much radiation there is when a drive harmonic
hits a coil overtone, as will happen by chance. Will you drive a
square wave into the base from a switching amp? No the voltage
needed will be too high - perhaps you are using a primary coil
or transformer?
