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 ...

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 have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

When using a power meter that references to a 50 MHz, 1 mW output power reference it is important to know that the 50 MHz reference is within the specified performance limits. The TEGAM Model 1830A RF ...

Here’s a situation that creates fear and trembling: The engineer receives a call from the radio station: “The transmitter is off the air and there is a VSWR fault.” If the station is fortunate, the ...

If you are involved in any sort of radio transmission, you probably have at least heard of SWR or standing wave ratio. Most transmitters can measure it these days and most ham radio operators have ...

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 ...
