If you have ever operated any sort of transmitting equipment, you’ve probably heard about matching an antenna to the transmitter and using the right co-ax cable. Having everything match — for example, ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer. Prior to its invention, measuring the response of an antenna system was more or ...

Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

You’ve probably seen old-time photos of radio setups with the station operator fiddling with the dials on the wireless radio setup, and also adjusting a large, wirewound (or copper tubing) coil. From ...
