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!

Subject: LF: 8 kHz loading coil
Hello (V)LF experimenters,
I have an idea of resonating my existing vertical on 8 kHz.
Is there a practical way to construct a 600 mH loading coil, withstanding
3-4 A and high voltage?
Any *large* toroids on the market?'
