RE: NEC-LIST:NEC model for coaxial collinear ( COCO antenna)

Well thank you for your idea

but ,if I'm not wrong ( I'm an user of NEC and not a pure
scientist in electromagnetic field modeling)
the thin wire approximation only implies that currents are not allow to flow
on a transversal path on the wire.

I was originally thinking at the use of transmission line model
to model the transmisiion line current
and than add wires to model the common mode current ( antenna current)
on the outer part of the shield of each cable section

The problem is that i do not completely understand
the usage of transmission line in NEC, in particulary in EZNEC

sincerely

I am pretty sure this is not possible as an actual wire model in NEC
because
of the use of the thin-wire approximation. There are some other
packages
written for student use that do address this problem to some extent, but
I
don't think it is available in NEC. Bill
