In the presence of a homogeneous heat current the isotropy of supetfluid 4He is broken and the propagation of second-sound waves becomes anisotropic. We calculate the angular dependence of the velocity and damping of second sound near T~ within model F of Halperin, Hohenberg and Siggia to leading or
