More generally, is there a modern software tool available
Hi Eric,
Many of us are using SimSmith for modeling anything that can fit on a
Smith Chart. Freeware, mature, runs in Java, imports Touchstone files
from measurements and antenna models (in EZNEC, the result of a
computation of complex Z and SWR over a user chosen bandwidth). It can,
for example, take an antenna measurement made in the shack, subtract out
the feedline, then put it back in with a matching network that we
design, compute and plot loss from fundamental models of >50 common coax
lines. Lots of optimization tools.
