WebThe VSWR is a measure of the matching of the antenna to the source and feeder cables. A low VSWR will minimize reflections from the antenna. VSWR Specification Definition When disclosing VSWR on test reports and datasheets, Halberd Bastion follow the BASTA reporting recommendations. 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.
