Abstract
A method for broadcasting, a signal, and an antenna system are disclosed. The antenna system comprises a feed horn and a reflector. The feed horn provides a radio frequency (RF) signal. The reflector is aligned with the feed horn and is illuminated by the feed horn, and comprises a reflective grid. The reflective grid lines are substantially parallel as viewed from a geographic location of a desired output beam from the antenna system. A method in accordance with the present invention comprises illuminating a reflector with an RF signal emanating from a feed horn, the feed horn being substantially located at a focal point of the reflector, wherein the reflector comprises a reflective grid, and reflecting the RF signal with the reflective grid, wherein lines of the reflective grid are substantially parallel as viewed from a geographic location of a desired output beam from the antenna system.
