We analyze the asymptotic directional structure and properties of gravitational field of specific exact solutions belonging to the large family of black hole spacetimes of type D found by Plebański and Demiański. We discuss the structure in the case of de Sitter (Λ > 0) and antide Sitter (Λ < 0) conformal infinity. With the aim of further interpretation, we have found the relation between the structure of the sources (the mass m, the electric e and magnetic g charges, the NUT parameter l, the

Keywords. Plebański-Demiański family of solutions -asymptotic directional structure of radiation -de Sitter, anti-de Sitter
