ABSTRACT:
An RF repeater arrangement for use in linking cordless handsets to a base station, has RF repeaters spaced from a common power supply unit and so distributed over an area to be serviced by the power supply unit that each of the RF repeaters is spaced from at least one other of the RF repeaters by a distance which is less than the range of coverage of the handsets. The power supply unit has a DC power supply connected to supply DC power to said a cable inner conductor, and RF repeaters each have an antenna for exchanging the radio signals with the handsets, transmit and receive circuits and a DC power pick-up connected to the co-axial cable inner conductor for powering the respective RF repeater.
