1. A wireless distribution system comprising:

  • a waveguide with a longitudinally consistent hollow cross-sectional structure and electrically conductive inner surface that supports the transmission of wireless signal energy from a wireless signal source to a location proximate to a wireless receiver location;

    a plurality of signal ports to inject and extract wireless signal energy; and

    a plurality of signal coupling devices coupled to the plurality of signal ports, each of the plurality of signal coupling devices includes;

    an impedance transforming section connected between an input port and an output port of each of the signal coupling devices;

    a conductor at least partially contained within the impedance transforming section;

    a signal probe inserted into the waveguide and coupled to the conductor, wherein the impedance transforming section and the conductor are configured to present to the signal probe a substantially conjugate impedance of the signal probe impedance when the signal probe is contained at least partially within an interior of the waveguide; and

    a signal radiating device is connected to the output port of each of the plurality of signal coupling devices.
