Specifically designed for the European DTH markets, this LNB provides optimized reception capabilities for receiving circular polarized signals on the high band. The LNB enables the reception of signals from one satellite and its distribution to maximum two Set Top Boxes with Single Tuner (or to one STB with Twin Tuner). It is factory-set for easy connectivity with any LO 10.75 Preset Set-top boxes, fully supports 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 the satellite broadcast reception across Europe.

The feedhorn is a part of the LNB and works like a directional horn. Its function is to capture the signals reflected from the dish and to shield the LNB from receiving extraneous radiation from other sources. These collected signals are then passed form the horn to the electronics within the LNB.
HsQuare is a unique waveguide technology which may be coupled with a slightly larger feed horn design to deliver better RF performances compared with common circular microwave waveguides.
