[TowerTalk] Insulated wire, theory

[Lux, Jim]

A discussion of how NEC4 does insulated wires (in short, by changing the 
wave number of the propagation in the conductor) can be found in the 
NEC4 Theory Manual.  Search for NEC4TheoryMan.pdf and there's several 
copies out there.


I suspect that EZNEC does it by a similar approach - changing the length 
of the wire to a slightly shorter length to accommodate the slower 
propagation in the insulated wire. That may have been done semi-empirically
