The MFJ-259 and 269 also can determine distance to fault. Look in the
instructions to see how to get to it.

I use a RigExpert antenna analyser in Time Domain Reflectometer mode. This
will show 'distance to fault' amongst other coax parameters. More reliable
than just doing an SWR sweep. Since the analyser tells you where the faults
lies, you can inspect the cable for trauma at that point or cut out the
poorly performing part and use the rest.
The RigExpert AA-230 is one of several amateur antenna analysers that have
this function, so checking coax in amateur stations is easy-peasy these
days! No need for megabucks test gear (even though it may be nice to have
for other reasons).
