  The relation between parameters the D/sqrt(I) and Ic/Isum and radiation
patterns of the optical and radio components of an extended radio source is
analyzed, where D and I are the apparent size and observed radiation intensity
of the source or its components respectively. The parameters of the pattern in
the optical and radio (1.4 GHz) ranges are estimated. The radiation pattern of
extended radio-emitting regions is close to spherical and the radiation of the
central component is concentrated in a 24 degrees wide beam. Its luminosity is
a factor of 4.58 higher than that of the extended component of the radio
source. The radiation pattern of the optical component of the radio source
turned out to be unexpectedly non-spherical: the main lobe of the pattern is
about 26 degrees wide. The g-band luminosity is 6.4-12.3 times higher than the
luminosity of the spherical fraction of the "optical" radiation pattern. A list
of 116 new giant radio sources is presented.
