Decameter wavelength radio emission is finely structured in solar bursts. For
their research it is very important to use a sufficient sensitivity of antenna
systems. In this paper we study an influence of the radiotelescope-antenna
effective area on the results of decameter solar radio observations. For this
purpose we compared the solar bursts received by the array of 720 ground-based
dipoles and the single dipole of the radiotelescope UTR-2. It's shown that a
larger effective area of the ground-based antenna allows us to measure a weaker
solar emission and to distinguish a fine structure of strong solar events. This
feature has been also verified by simultaneous ground- and space-based
observations in the overlapping frequency range.
