The results of interferometric researches of the quasar 3C216 have been presented. The model of brightness distribution of the quasar at frequencies of 20 and 25 MHz and spectra of its details at frequencies below 1 GHz have been refined. It was found out, that at decameter lengths the radio image of 3C216 has three components. It consists of a compact component having the size limited by scattering, an extended component with the size of 4.5″ and a halo with the size about 23″. The northeast hot spot (instead of the core, as it was supposed earlier) is the dominating compact component at decameter waves. The self-absorption effect in the northeast hot spot has been detected.
