Bridge Tap; Water Ingress; Load Coil - Radiodetection 1205CXB Operation Manual

Bridge tap

Bridge
tap
503.3ft
A bridged tap will appear as a downward or negative
reflection, because the impedance reduces at the
point of the tap, sometimes followed by an upward
reflection caused by the end of the tap.

Load coil

Load coil
147.3m
A telephone network load coil will cause an
upward, high impedance reflection similar to an
open circuit. TDRs are generally unable to "see"
past a load coil
