Abstract :
A correcting feed, illuminating a 600-ft circle of the Arecibo Ionospheric Observatory reflector, has been built at 611 MHz. The feed has two major components, a four-element linear array with a reflecting screen and a 16-element linear array. The antenna gain is 56 dB and the 3-dB width of the principal lobe is about 9 minutes of arc.
