If your load ( antenna ) is EXACTLY 50 OHM's.
AND
your load does not have ANY inductance or reactance ( J +/- Zero ),

Then, and only then you length of coax does not matter.

If you have to RE-TUNE your amplifier after switching from your dummy load to antenna ( assuming the dummy load IS 50 OHM's and most of them are), your antenna is NOT 50 OHM's.

++++++++++++++++++++++++++++++++++++++++++++++++++++

If your antenna is NOT + or - J zero, your SWR meter is reading incorrectly.
