An infrared IR radiation emission surface in a predetermined wavelength range comprises a substrate made of a material based on silicon carbide SiC, and an ensemble of texturing microstructures covering the exposed emission face of the substrate. Each microstructure is formed by a single protuberance, which is arranged on and integrally with the substrate. The microstructures have the same shape and the same dimensions, and are distributed over the face of the substrate in a bidimensional periodic pattern. The shape of each microstructure is smooth and regular, with a radius of curvature which varies continuously from the apex of the microstructure to the exposed emission face of the substrate.

A satellite dish mount device for mounting a dish base plate of a satellite dish thereon. The satellite dish mount device includes a flashing attached to a rooftop. The flashing includes a cable receiving member. A base mount block assembly is integrated to the flashing and includes a block member and a top base plate adaptable to mount the dish base plate thereon. The top base plate includes a plurality of first extruded fins and a plurality of second extruded fins. A cable riser assembly enables a cable coupled to the satellite dish to pass via the cable receiving member through the rooftop. The cable riser assembly provides a drip curve arrangement to the cable above the rooftop and between the satellite dish and the strain relief fitting member thereby providing water proof protection to the cable riser assembly and to the rooftop.
