VSWR - Return Loss - Γ  Conversions

These are the standard set of equations for converting between VSWR, return loss, and reflection coefficient (Γ). A table of convenient values are presented at the bottom.

Here is a JavaScript calculator for VSWR / Return Loss / Reflection Coefficient / Mismatch Error / Improvement
