• TLDetails - Transmission Line Details. 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. If you are using a moderately fast computer you can hold down a spinner and "watch the movie" on the charts as the results are recomputed. By AC6LA
