For whatever it's worth, I measured the loss in my main run of CATV 
hardline right after it was installed, as well as the SWRS of the various 
antennas connected to it with pigtails of flexible coax.  I just look out 
for any change in those values.  At the point when I see one, within the 
accuracy of my simple equipment, I'd assume the coax or a connector was to 
blame (the coax if gradual, a connector if abrupt).
