Sure, there is ALWAYS VSWR. It may be 1:1, but it's always there.

If there's no reflection, there can be no standing wave. So, being
pedantic, there's no such thing as an SWR of 1:1!




Wrong. An SWR of 1:1 indicates a perfect match, with no reflected
power. It is recognized by all electronics texts and experts.

My suggestion would be for you to learn some transmission line theory.
Your statement here just showed you have no knowledge of it at all.

Even when I took my novice test many years ago I had to understand SWR
better than that.

The point I'm trying to make is not technical. It's simply one of verbal
logic. Without the presence of a standing wave, you can't possibly have
something called a "standing wave ratio". But, like all RF engineers, an
SWR of 1-to-1 is something I too strive to achieve!

It doesn't matter what your verbal logic is, Ian. The correct term is
"Standing Wave Ratio", and an SWR of 1:1 means there is no reflected
power and you have a perfect match.

That is the technical definition of a technical term.
