Rick,

I already corrected this misunderstanding once: for a 2:1 SWR the
maximum voltage will be 1.414 times the matched voltage, not double! The
minimum voltage will be 0.707 times the matched voltage.

If V is the matched line voltage, Vmax=1.414xV and Vmin=V/1.414 giving
Vmax/Vmin=2:1

Yes, we all know this, but power loss is proportional to the
SQUARE of the voltage, so it is doubled for 2:1 SWR in the worst
case.  Am I missing something?
