I know how EZNEC calculates propagation from straight wires. It does

But do you know how it calculates the inductance of coils?

I don't think EZNEC cares about the inductance of helical
coils. As I have been advocating, the EZNEC helical option
treats the coil as just another part of the wire antenna
that has been spiraled into a coil.

It is ironic, is it not, that EZNEC treats a helix as just
coiled up wire? Especially after the gurus have asserted
that a coiled up piece of wire is not a piece of wire at
all but is instead transformed into something magical that
violates the theory of relativity with faster than light
propagation?

How long has it been able to do this?

I don't know exactly. I was creating segmented coils long
before EZNEC had the helix option. I even wrote a BASIC
program to generate an ASCII file capable of being imported
into EZNEC.
