Looks complex to manage with a
thin wire. I made a two layer coil with 1.5mm2 wire using this
technique and the thick of the wire helps a lot
to keep turns in place. Thinner
wire may be doable with much more layers ..... may be ?
I do not recommend it.
BTW, before starting to wind a coil it would be useful to know the
target value :-) So you need to know the antenna C and thus you need to
have an existing antenna.
Do you already have your VLF antenna installed between the buildings /
What is the C?
Ah and btw it is worth to use a wire which has at least 1 mm diameter,
better is 2 mm because of HV partial discharges (audible and visible
and lossy and unstable-phase)!
If you have access to the high houses, you could even use 10 or 20
wires in parallel, spaced 0.5m or so. That would be ideal and the C
would be high, voltages low and L low!
