could work. In the capacitive near-field range, the
voltage * capacitance * effective height / (2 pi epsilon0) /
10 kV on your antenna capacitance and height, you'd
get about 0.15 mV/m
at 2.4 km, maybe 14 dB stronger than ZEVS.
Take care! Touching
10 kV on 136 kHz will
severly burn you. But on 136 Hz it would kill you, unless
is safely limited to a few mA.

Betreff: LF: ELF communications ?
This afternoon i'm attempting to transmit on my INV-L on 136.172 Hz (not
kHz!). Just preparing my H bridge VLF PA and i intend to use an old 10
kV transformer which i got from an old furnance (to inflame the oil
Will that work on 2.4 km distance? It's well inside the near field.
Which mode could be possible? QRSS-3? CW?
The 2200000 m band, or 2.2 Mm band :-) A near field of 350 km !!
I hope i can apply 10 kV to the antenna. It will not be resonated. And
maybe i will see harmonics as well, because the input is rectangular...
