"---Running only 100 Watts?"

At resonance, you should have 85 volts at the dipole drivepoint. If
there were no radiation from the antenna, voltage at its tips would rise
to 170 volts from the Ferranti effect, that is the voltage doubling from
collapse of the magnetic field caused by current interruption at the
conductor`s end.

It`s possible to build a Tesla coil with inductive loading of an
antenna, but if you don`t do that, there`s not much chance of generating
enough voltage to make a corona with 100 watts. At a kilowatt you only
have 3.16 X the volts at 100 watts. It takes several thousand volts to
generate a corona at normal atmospheric pressure.

Install a fire detector and be comfortable.
