Abstract

The results of an experimental study of patterns of the three-band feed for a small VLBI2010 compatible radio telescope reflector antenna are presented. Differences of the behavior of experimental three-band feed patterns and requirements specification for feed-prototype [1] are brought to light. A new engineering solution of the three-band feed unit has been suggested.
