Now, now, boys, be nice. Both of you can be right if you are not
talking about *power* gain. Since you are discussing VSWR, rho can be
greater than one AND the voltage return gain can be greater than one.
The voltage across a resonant circuit depends upon the 'Q' and can
certainly be higher than the applied incident voltage. For that exact
same reason, Vref can be higher than Vfor. It occurs when the load is
the conjugate of Z0 and Z0 is not purely resistive.
