Not sure that is a real objective measurement ... as in if the
losses of the coax were to go higher, will the SWR change much?
What I did/do ... is measure the actual power at the antenna using
a wattmeter ... note the date/band/etc. ... and then can compare
THAT known data against the same test at a later date.
Doing that can also be a reality check as to WOW ... the losses
on the higher bands really do exist!
More than once in the past 33+ years <sigh> have I been 'lulled'
into thinking all was well just because the antenna SWR looked OK.
