DEFINITION

Classification: 343/912

(under subclass 907) Subject matter wherein the component constitutes a conductive structure (usually metallic) which is adapted to return or to reradiate into free space a substantial portion of the impinging radio wave energy coming from or going to an associated active antenna.

(1) Note. The reflectors or directors of this subclass are adapted for use with an active antenna associated therewith, and facilitate transmission or reception of this antenna in a desired direction. See this Class 342, particularly subclasses 1-20 for reflectors which have no active antenna directly associated therewith, but which render their presence known by reflecting energy from and to a remote antenna.

833, and the search notes thereunder, for the combination of a director and active antenna.

834+, and the search notes thereunder, for the combination of a reflector and active antenna. 878+, for reflectors or directors with supports therefor.
