Abstract

The main requirements for the feed array designed for the RATAN-600 radio telescope, which are intended to improve observational possibilities, are presented. The experimental eight-element feed-array assembly and its measured characteristics are described. The first antenna measurements, made in the AC operational mode, shown that the combination of the reflector with the feed array may increase the reflector´s facility. The equipment described could be used for radio-astronomical observations at the RATAN-600, but it is clear that the best results will be achieved with the use of a 32-element feed array.<>
