parabolic antenna designed to receive analog and digital signals at the same time, producing hot water using solar energy.

摘要

The prototype consists of a first frontal part made of plastic material (transparent) ultraviolet rays resisting, behind this a metallic antenna with mat black painting hot temperature proof. A following pipe network enables a thermic exchange between the interceptive antenna and the exchanger liquid. The fourth layer is an heat insulator. A further paraboloid is the last component of the assemblage and supports the whole structure. This antenna can be used with any satellite system and at the same time can be connected to a heat exchanger for the storage of water warmed up in the sun. The exchanger can be placed under the antenna by means of a differential thermostat together with a circulating pump, or above the antenna without needing any thermostat or pump because the circulation takes place naturally. The above unit can be manufactured both offset and prime focus.
