How to interpret traces?
answer
A return loss measurement is like using a SWR meter, it is a quick pass/fail type of measurement. DTF is used to identify where a problem occurs, your knowledge of the installation will indicate the type of problem. For example, a large spike in the middle of a main feed line indicates a problem. In some areas of the USA, cables make excellent target practice and bullet holes are common. A large spike typically indicates an open or short of some type. Somewhere in the middle, a crushed cable, ignoring the antenna.

One thing, on long cable runs, you can use either VSWR or RL in DTF. For short cable runs, like jumpers, VSWR sometimes makes it easier to interpret the display.
