Regarding VSWR:
I would think that increase in effective current does cause greater (I*I)*R
losses (ohmic)...

.... also, an effective increase in voltage also causes increased (E*E)/R
losses in the dielectric itself...

But, what kinda of losses are we talking with both these, under 1db? (no
irate flames, please)

to have misplaced some already!!!
