By transmitting a transmission signal with the use of this pilot signal, between a transmitting device and a receiving device, it is possible to carry out channel equalization by complex information which is obtained from a pilot symbol. In particular, these offsets are controlled by both coarse and fine adjustments. An airtight hinge connection is integrated in the flap so that, on the side of the flap protected from the wind, a turbulence system which improves the flow conditions is formed. Other decorative elements may be included such as interior scenic landscapes in bright colors and a plant placed on the exterior top of the housing.
