Questions

VSWR Calculator (Voltage Standing Wave Ratio Calculator) FAQ

Can I enter reflection coefficient to get VSWR?
Yes, the calculator works both ways; entering the reflection coefficient gamma computes the VSWR and related loss values.
What does a VSWR of 1:1 mean?
A VSWR of 1:1 indicates perfect impedance matching with no reflected power, meaning 100% of the input power is transmitted to the load.
How is return loss related to VSWR?
Return loss and VSWR are inversely related; as VSWR increases, return loss decreases, indicating more signal reflection and poorer matching.
Can I use this for antenna system design?
Yes, the tool is suitable for evaluating antenna feed lines and transmission systems, though results assume ideal cable conditions.
