Christer,

With the figures you give I estimate you will be getting about 100 KV across
the inductor. An air-cored coil , of substantial size, would seem to be the
best way of doing things.

By the way, in the early days of Rugby Radio (GBR) on 16 kHz they had some
trouble with their loading coil . It appears that it overheated, and set
fire to the wooden building in which it was housed!

I visited Rugby in about 1951. From the loading coil the feeder cable
ran up though a circular window high up in the gable end. The clearance
was about 2 feet but the wooden surround was burned and charred from
flash over. When the Tx was keyed you could see the loading coil flex
and jerk!
