Abstract :
The radiotelescope BSA FIAN, constructed in 1974 in Pushchino Radio Astronomy of Astrospace centre of Physical institute of Russian Academy of Science (PRAO ASC LPI), is one of the most sensitive tools in the meter wave range. In 1998 the radiotelescope was reconstructed to be interference free, working in range 109-113 MHz. The dipoles, feed lines and pattern forming system were changed. The matrix for forming the 16 beam pattern is presented. This matrix is constructed from coaxial hybrid rings.
