| VSWR | Return Loss | |Γ| | Mismatch Loss | Power Reflected |
|---|---|---|---|---|
| 1.0:1 | ∞ dB | 0.000 | 0.00 dB | 0% |
| 1.2:1 | 20.8 dB | 0.091 | 0.04 dB | 0.8% |
| 1.5:1 | 14.0 dB | 0.200 | 0.18 dB | 4.0% |
| 2.0:1 | 9.5 dB | 0.333 | 0.51 dB | 11.1% |
| 3.0:1 | 6.0 dB | 0.500 | 1.25 dB | 25.0% |
| 5.0:1 | 3.5 dB | 0.667 | 2.55 dB | 44.4% |
| 10.0:1 | 1.7 dB | 0.818 | 4.81 dB | 66.9% |
Formulas:
Γ = (VSWR − 1) / (VSWR + 1)
Return Loss = −20 × log₁₀(|Γ|) dB
Mismatch Loss = −10 × log₁₀(1 − |Γ|²) dB
Power Reflected = |Γ|² × 100%
Γ = (VSWR − 1) / (VSWR + 1)
Return Loss = −20 × log₁₀(|Γ|) dB
Mismatch Loss = −10 × log₁₀(1 − |Γ|²) dB
Power Reflected = |Γ|² × 100%
