I am vaguely aware that for a 2 wire line, EZNEC recommends that you
replace it with the EZNEC transmission line element.  It also says
that EZNEC will not model the effect of the line in common mode, AFAIK.
In any event, the FCP consists of 3 parallel wires.  I have no idea
what to do with such a structure.  So perhaps there is no problem
modeling an FCP; it's just that I haven't got a clue.  I would
be happy to learn how to do it.  Could you explain what to do or post an 
EZNEC file?
