BTW. Those 24kV at 800 W can explain some pictures shown in this reflector ;-)

I know someone who has up to 45 kV rms on his LF antenna...

Will test it at low power first and see what happens. Think I can measure induced voltage on motor coils and this will show the risk of increasing power

Can't you remove the cable of the motor so it is floating at high potential too?

I'm still in the process of getting access to the fire extiguish pipe to clamp a wire up to the antenna. It is not easy, but can be done

That sounds fine!
