Abstract: The present invention addresses apparatuses, methods and computer program product for providing improved distance to fault measurement for voltage standing wave ratio (VSWR) on antenna line in networks. An embodiment of he present invention comprises the steps of transmitting a signal to a line to be tested, capturing a forward signal of the signal, capturing a reverse signal of the signal, separating the reflection of the signal in time domain via cross correlation of the forward signal and the reverse signal, and detecting a distance to fault in the line by searching and processing maximum peak position of the captured and separated signals.
