  Radiative properties of gravitational and electromagnetic fields generated by
uniformly accelerated charged black holes in asymptotically de Sitter spacetime
are studied by analyzing the C-metric exact solution of the Einstein-Maxwell
equations with a positive cosmological constant. Its global structure and
physical properties are thoroughly discussed. We explicitly find and describe
the specific pattern of radiation which exhibits the dependence of the fields
on a null direction along which the (spacelike) conformal infinity is
approached. This directional characteristic of radiation supplements the
peeling behavior of the fields near the infinity. The interpretation of the
solution is achieved by means of various coordinate systems, and suitable
tetrads. Relation to the Robinson-Trautman framework is also presented.
