: Computes Standing Wave Ratio (SWR) at both the input and the load. Physical Parameters : Returns precise characteristic impedance ( cap Z sub 0
The remains a worthwhile pursuit for any RF enthusiast who values efficiency, accuracy, and a classic interface. While it may take a few extra minutes to locate a clean copy and configure compatibility settings on Windows 10 or 11, the payoff is a tool that launches in under a second and gives you answers that high-end commercial software would require multiple mouse clicks to reveal.

TLW, originally developed by (Dean Straw) and later refined with contributions from the ARRL (American Radio Relay League), is a freeware utility designed to calculate the input impedance, SWR, loss, and phase delay of any transmission line given its characteristic impedance (Zo), electrical length, velocity factor, and load impedance.
