摘要：A radio frequency (RF) signal coupler (120) for cooperative engagement with a shunt device (110) and for cooperative engagement with an RF mode. The shunt device has a high voltage terminal (112) connected to an electrical cable of the power network (111) and a low voltage terminal (114). The coupler comprises a signal lead (123) connected to the low voltage terminal of the shunt device, a ground lead (132) connected to earth ground, and a coupling transformer (130). The coupling transformer comprises a ferrite ring (124), a multiple turn primary winding (126) having a first end and a second end, the first end being connected to the signal lead and the second end being connected to the ground lead, and a multiple turn secondary winding (125) having two terminals for providing the RF signal to th RF modem. The ratio of turns of the secondary winding to the turns of the primary winding is at least two to one.
