Well, yes, Gary, that's true.
But suppose it's 1.2:1? is that because it's 1.2:1 at the
antenna, or because whatever wierd impedance is presented at the
feedpoint is transformed to something close to r50 j0?

Seeing 1:1 swr at the shack means that the swr at the antenna is also 1:1
(provided you don't have excessive feedline loss). Swr will be the same
anywhere on the line.
