Let's start a parallel thread on the effect of coating a 14-gauge
antenna wire with a thick layer of ferrite. Say 1mm thick,
permeability = 100.

Would this have any effect on velocity factor? If so, by how much?

Why not start with an insulating material like Teflon?
That's what the previous discussion was about. Given
the dielectric constant of Teflon and the thickness,
EZNEC+ 4.0 will take the VF into account.
