RE: NEC-LIST: CFA modeling results

Hi,

  I have a question about CFA modeling.

  The phase relation between the disk and the cylinder is clear, but
how about the amplitude? I read the NAB99CFA paper (
http://www.antennex.com/preview/cfa/nab99cfa.htm ), it seems that CFA
not only require E and H in-phase but also |E|/|H|=377ohm. So it seems
that the amplitude of the feeding to the cylinder and disk may not be
arbitrary.

  Another page( http://www.antennex.com/preview/Folder02/cfa_5.htm )
gives an instruction about the feeding network. How to model it with
NEC?

  I do not know whether my understanding is correct.
