Abstract

A repeater for use in connection with enhancing reception of wireless communications in an architectural structure utilizes a housing that incorporates both a null antenna capable of being oriented to provide an antenna beam directed into an interior portion of the architectural structure, and a repeater circuit that is configured to provide bi-directional exchange of radio frequency signals between the null antenna and a donor antenna. The donor antenna may also be mounted to the housing, or alternatively may be coupled to the housing via a cable or other communications path. The repeater is suitable for installation in an attic, or alternatively, within a room or other inhabitable area of a structure.
