How do you know it's a "pure cosine wave," Cecil?

Because Kraus says so?

That's interesting. It means we don't need to use
NEC any more.

As I said previously, it's only a pure cosine wave for
a thin-wire dipole. NEC handles more than thin-wire
dipoles.

The coil adds a bulge to the thin-wire cosine wave but
the overall envelope is clearly visible.
