Principles of transmission lines
A transmission line is a device designed to guide electrical energy from one point to another
PL-259 to Coax Installation Done Right
I have hundreds of silver plated PL-259s in service at my station. They are all soldered the same way
Quarter Wave Line Matching Transformer
to calculate the impedance required for a 1/4 wave electrical section of line
Quarter wave impedance transformer
A λ /4 line is, in effect, a transformer, and in fact is often referred to as a quarter-wave transformer
Receving splitter
For feeding the RX inputs of both my Elecraft K2 and TenTec Orion with the same RX antenna, I'm in need for an antenna splitter
