In view of the fact that power is proportional to the square of the voltage, it is very easy to create a VSWR formula in terms of the forward and reverse power readings. VSWR = 1 + P ref P fwd 1 - P reef P fwd. These formulas enable the VSWR existing in a feeder to be calculated in a variety of way dependent upon the parameters that are available.
