scope:

The present document addresses the requirements for directional fixed beam antennas to be utilized with new Point-to-Point (P-P) systems operating in the frequency band 1 GHz to 3 GHz. Electronically steerable antennas, and circularly polarized antennas will not be considered under the present document. The application of these Digital Radio Relay Systems (DRRS) is anticipated to be for P-P links in local, regional and national networks, mobile base station connections, customer access links, telemetering and telecontrol (including transportable and offshore use).
