WebHigher values of VSWR indicate more mismatch loss. As an example of common VSWR values, a VSWR of 3.0 indicates about 75% of the power is delivered to the antenna (1.25 dB of mismatch loss); a VSWR of 7.0 indicates 44% of the power is delivered to the antenna (3.6 dB of mismatch loss). Webwaveform would measure exactly the same as the sine wave coming from the transmitter. This is called a matched condition and is what Understanding SWR by Example Take the mystery and mystique out of standing wave ratio.

WebGovInfo U.S. Government Publishing Office taxes itemize home improvementWebNext, when the VSWR and/or return loss is known, you can also determine the percentage of reflected power. A VSWR of infinity (infinity:1) would have 100% of the power reflected back. A VSWR of 1.0:1 would have 0% of the power reflected back. With all VSWR values between infinity and 1, some percentage between 0 and 100 is reflected. the chicken hearted monster

"WebB- SWR Measurement Procedure. The VSWR meter may be used to measure a standing wave ratio as a direct reading or as a decibel reading to be converted to SWR. Normally the measurement of SWR will lie in a range from 1:1 to 10:1 (low). However, measurements greater than 10:1 (high) may be made. The " - Measurement of low and high vswr
