Abstract :
The field of sight of Double Reflector Spherical Antenna of Radiooptical Telescope ROT-54/2.6 (Orgov, Armenia) does not concede to a field of sight of parabolic antennas, and at the fast scanning of the pattern beam on 10 beamwidths through the switching of feed array elements the directivity parameters of the antenna almost does not deteriorated.
