Abstract. Software was developed for calculating the dimensional parameters of an antenna such as a 12-element wave channel for the VHF band. For the calculated frequency of 1421 MHz, the dimensional parameters were analyzed using the MMANA software antenna analyzer in order to evaluate the effectiveness of the algorithms embedded in the program. The distribution of currents in the antenna, radiation pattern, bandwidth, antenna gain depending on frequency are given. By measuring parameters, an antenna was created, which was included in the design of a portable radio telescope. As a result of field tests of the radio telescope, emission spectra were obtained in the frequency range 1300-1550 MHz in the direction of the constellation Cassiopeia.
Key words: radio telescope, Yagi-Uda antenna, radiation spectra in Cassiopeia, software.
