Abstract :
The paper describes a feed which was built for the 120-foot diameter Cassegrain antenna system of the Haystack radar. With this feed the system will operate over a band of frequencies from 7700 to 8400 Mcps, and it will produce a pencil beam of total half-power width of about 4 minutes of arc. The system will radiate a signal level as high as 100 kw average, and it will provide monopulse tracking with circular polarization.
