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 ...

A standing wave may be formed when a wave is transmitted into one end of a transmission line and is reflected from the other end by an impedance mismatch. The Voltage standing wave ratio is the ratio ...

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 ...

Knowing the directivity specification of your measurement device can go a long way in setting measurement expectations. Directional power measurements are important when determining transmitter output ...

Standing waves are one of those topics that lots of people have a working knowledge of, but few seem to really grasp. A Ham radio operator will tell you all about the standing wave ratio (SWR) of his ...
