HI Tony,

the final MOSFETs are specified with : 'no destroy'  at a load VSWR=20:1(All
Phase).
So no concern, if your meter even shows 3:1 equal 50 percent reflected power
for a short period of time. On the other hand it makes no sense to run a
antenna with 3 dB mismatch.
Excessive mismatch endangers the finials due to therminal stress and/or RF
voltage issues, but usually no problem for the driver or actually your
exciter board Hermes.
