Which SWR value indicates a perfect match between transmission line and load?

Explanation:
When the load perfectly matches the transmission line’s impedance, all the power is absorbed with no reflections returning toward the source. This yields a Standing Wave Ratio of 1:1, indicating a pristine match. Any other value shows some energy is reflected due to mismatch, so 1:2, 2:1, and 3:1 are not perfect matches. The 1:1 value is the standard for a flawless impedance match.
