disclosed is a power line broadband communication system having broadband coupler devices capable of direct electrical connection to an energized power line . the coupler includes a conductive portion movable by an adjustable member from a non - conducting retracted position spaced apart from the power transmission line to a forward conducting position in electrical contact with the power line . an insulated arm supports the coupler on the power line . a base on the coupler is engageable with a remotely activated tool in order to accomplish the electrical connection in a safe and secure manner . broadband data signals are sent to and from customer premises along the shared energized power lines . new coupler connections to the energized power lines allow the additional broadband customers and / or repeaters to join the communication system . also couplers may provide connections to control electronics , routers , wireless transceivers , and may allow the broadband signals to bypass transformers on the power lines . the invention helps to minimize risk by allowing an installer to be remotely spaced from the energized power line while making the electrical coupling contact with the energized power line .
