In the case of the offset satellite dish, the LNB does not project any shadow on the reflector. In this case, the focal point (point in the reflector at which the reflected signal aims) is not placed in the centre but on the side, which allows for optimum performance.
Steel - an iron and carbon alloy - is 100% recyclable and degradable; Televes thus meets its own requirements in terms of respecting the environment. It is a robust and highly-resistant material that endures extreme variations in temperature, which makes it suitable for use in satellite dishes.
