I do that with my MFJ-259. :-)
Sweep a wide range and look at peaks and nulls, or use distance to fault.
Dips repeat at 1/2 wave intervals. The firmware inside converts that to feet
on distance to fault. I can locate a cable break on 3000 foot cables within
a few feet.
Not only that, with a toroid to inject common mode signal from the 259 and
portable receiver with small loop, I can locate the cable under ground!!
It makes hours turn to minutes.
