The SD 18 Sunshade is resistant to the heat generated by direct sunlight and UV radiation. It is particularly space-saving and can be extended horizontally without transitions. The rear side can be used flexibly. On the one hand, fittings and other components can be mounted directly on the rear wall. On the other hand, the SD 18 Sunshade can be mounted to a transmitter with a bracket. This gives the unit additional protection from the side.
