Transmission Line Details TLDetails
http://www.qsl.net/ac6la/tldetails.html
This utility program shows the impedance and SWR at both ends of a transmission line and the details of power loss in the line. It includes characteristics for over 40 built-in line types. You can modify these values to see how small changes affect the results or to specify custom lines. All program inputs may be changed directly or you can use spin buttons to make the changes.
XLZIZL
http://www.qsl.net/ac6la/xlzizl.html
XLZIZL is an Excel application that analyzes the components of an antenna feed system, including transmission lines, stubs, baluns, and tuners. Calculations include impedance transforms, SWR and reflection coefficient, power loss, voltage and current standing waves, stress on tuner components, network attenuation (S21), and return loss (S11). Analysis results are available in worksheet format and in five different chart formats, including Smith charts.
