ABSTRACT:
A communication device is arranged to send a communication signal in the form of code pulses down an electric fence line which is energized by electric pulses from a fence energizer. The code pulses are generated to be distinct and separate from the electric pulses generated to energize the fence. A controller is included to control the charge and discharge of an energy storage device to generate at least the code pulses to be transmitted along the electric fence line. A coupling device is also included to couple both the code pulses and the electric fence energizing signal to the fence.
