new and improved 9 to 1 linear matching transformer that is used on the radio end of the feedline
Band-pass filters
There are applications where a particular band, or spread, or frequencies need to be filtered from a wider range of mixed signals
Cable impedance
This document tries to clear out some details of transmission lines and cable inductance
