4.1.2.2 Coupling using special connection accessories
Coupling via adapter
cable
The signal from the transmitter can be directly coupled into plug sockets, antenna
connections and telephone jacks with the aid of a suitable adapter cable. In doing
so, it is not necessary to disconnect the lines.
Megger offers a ready made house connection set for this type of coupling (also see
section
Coupling via transmitter
clamp
The transmitter signal can be coupled onto easily accessible cables with the aid of a
transmitter clamp. In doing so, it is
not
necessary to disconnect the cables.
By ensuring that the transmitter clamp is completely closed around the cable, only a
small leakage field will be generated. This can significantly reduce the unwanted
coupling of the signal onto neighbouring lines.
Ideally the cables will be grounded at both ends; but even if they are not grounded at
one end, selecting high power transmitter output will assist easy location.
