VSWR (Voltage Standing Wave Ratio) is a metric commonly used with antenna systems for ham or shortwave radio communication.VSWR is normally defined as a ratio with a 1:1 VSWR, indicating that there is an exact or perfect match between all antenna system elements.SWR (Voltage Standing Wave Ratio) is a metric commonly used with antenna systems for ham or shortwave radio communication.
Time-weighted return. The time-weighted return (TWR) (or true time-weighted rate of return (TWRR)) is a method of calculating investment return. To apply the time-weighted return method, combine the return over sub-periods, by compounding them together, resulting in the overall period return. The rate of return over each different sub-period is weighted according to the duration of the sub-period.
