There will be resonances in the entire line that

Ideally, not if the SWR is 1:1 on the 50 ohm coax
in which case, the RMS voltage and current is constant.
Such a line is known as a "flat" line. At any point up
and down the line the ratio of voltage to current
is 50 ohms.

That's the part of me that ran down my daddys leg.
