[Amps] Does coax loss depend on SWR?

[Steve Katz]

Sure it does (loss change with SWR).

Specified attenuation is almost always at SWR = 1.0.

It increases above that.

There's a pretty good on-line calculator here:

Scroll down to the calculator and fill in the blanks.

Does coax loss depend on SWR?  Coax operating under high SWR must be
able to
deal with the extremes of current and voltage along the line, but are
any
more watts lost along the way than if the line was operating at 1:1 SWR?
