[Antennaware] feedline modeling

[Paul Decker]

Hi Group, 



Using EZ-NEC, is it reasonable to model an open wire feed line, for example a 600 ohm ladder line using two parallel wire segments shorted at each end by two other wire segments, one end being the source, the other being the load? 



I know I can add a transmission line and change the impedance, but what about if I'm modeling the "special" transformation properties of specific lengths of transmission lines?  



If not, how is this done?    



thanks,
