We analyze the asymptotic behaviour of gravitational and electromagnetic fields which are generated by uniformly accelerated pair of charged black holes in asymptotical de~Sitter spacetime. Such situation is described by the de Sitter C-metric, the solution of Einstein-Maxwell equations with a positive cosmological constant. The interpretation is achieved by employing suitable tetrads parallelly propagated along null geodesics. We explicitly 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 structure of radiation supplements the peeling behaviour of the fields near infinity.
