WebIn review, this tutorial describes SWR or VSWR as a way to measure transmission line imperfections and efficiency. VSWR is related to the reflection coefficient. A higher ratio depicts a larger mismatch, while 1:1 ratio is perfectly matched. This match or mismatch arises from the standing wave's maximum and minimum amplitude. WebGenerally speaking, if an antenna analyzer or (other) transmitter shows that the antenna output presents a SWR of 1:1, then ... We could compensate with an amplifier, but high-power amplifiers are expensive, and big, and hot, etc. ...
