Splitters for installations from 5 to 1000 MHZ. These elements accomplish shielding or screening requirements specified in the european norm in force, specially concerning to electromagnetic compatibility. European norm EN 50083 section 2 (and 2/A1) specifies screening levels that passive elements must accomplish in distribution systems of TV and sound signals through coaxial cable. In this norm are defined levels and grades of quality of passive elements. Elements that accomplish A CLASS specifications, see attached board, for its screening are specially recommended to be used in distribution networks which are exposed to high levels of interferences in environment. This new series of passive elements FTE Maximal fulfill A CLASS requirements of this norm. References with these features are marked as A.
