Hi,

If EZNEC reports a source impedance for a balanced antenna, such as
a loop, of R+-jX ohms, and I am trying to match the antenna to the
line: I am using a Smith Chart program that is unbalanced i.e.
everything is respect to ground. Question is, what impedance do I
enter into the program such that I will get the correct matching
solution for the balanced antenna? I have used this program numerous
times and it works well for verticals, mobiles, and other unbalanced
antennas. Thanks.
