Specifically designed for the European DTH markets, this Monoblock LNB allows for dual satellite reception. It can be used for satellite broadcast reception (on an 80cm dish antenna) of any two satellites spaced with 6°. This LNB enables the signal distribution to maximum four Set Top Boxes with Single Tuner (or two STBs with Twin Tuner). It is optimized for High Definition transmissions and provides excellent Noise Figure performance. Designed to meet strict specifications and manufactured to the highest industry quality standards, this LNB is an ideal solution for satellite broadcast reception across Europe.
<b> Main Features</b>
