Abstract
We use experimental data of the FIRST survey to construct the radiation pattern of external components of extended radio sources. The radiation pattern differs from spherical. The greatest deviation from sphere is observed in the region facing the central component, where there is a deep minimum. The minimum of radiation in the beam pattern is associated with the region where the regular magnetic field of the jet transforms into entangled magnetic field of the external component. Perhaps the minimum is determined not only by the component’s radiation, but also the screening by structural elements of the extended radio source.
