This is called a matched condition and is what Understanding SWR by Example Take the mystery and mystique out of standing wave ratio. Darrin Walraven, K5DVW Table 1 SWR vs Reﬂected Voltage or Power VSWR Voltage Power Reﬂected (%) Reﬂected (%) 1.0:1 0 0 WebNext, 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. how to fill colour in cell using vba
