These points are plotted at A (for power) and B (for voltage) in Fig. 26.5. The voltage standing wave ration (VSWR), often shortened to standing wave ratio (SWR), can be defined in terms of the reflection coefficient, G: = + Γ VSWR 1 1 − Γ (26.10) or VSWR = 1 + Γ 1 − Γ PWR PWR (26.11) Using the results of Example 26.2, + VSWR = 1 0.28 1 − 0.28 1 = + 0.529 1 − 0.529 1.529 = = 3.25 : 1 0.471 or, in decibel form, VSWR dB = 20 log (VSWR) = 20 log (3.25) = (20) (0.510) = 10.2 dB (26.12)
