Our data for sources with steep radio spectrum, detected with radio telescope UTR-2 at the decametre band give evidence on the great luminosities, linear sizes, characteristic ages of these objects. In connection with such peculiarities, we examine the luminosity-linear size relation of galaxies and quasars with steep radio spectrum at the decametre band. It turned out, that this relation has similar trends for considered radio sources with linear steep spectrum and break steep spectrum. Also we presented the luminosity ratio-linear size relation at different frequency ranges. We discuss the obtained evolution relations for galaxies and quasars with steep low-frequency radio spectrum.
