Oops. I meant, WHEN RECEIVING, fiddling with the antenna or the
antenna/feedline match won't have any effect at all on the line SWR. It
will, of course, change the line SWR when transmitting.

However that doesn't mean that it's unimportant to match the feedpoint
impedance of a rx antenna to the feedline connected there.

A rx antenna with a mismatched feedline will not deliver to the rx end of
the feedline the maximum possible energy available from the fields in which
that antenna is immersed. Whatever received power that is reflected by a
mismatch at the rx antenna feedpoint is re-radiated (less losses).
