Opticum LNB Quattro Flange C-120 Full HD, 3D


Inverto’s high-performance Ultra LNBs were specifically designed to address the need for superior reception under the edges of the satellite footprint skirt, small dish sizes or long coax cables. Thanks to its novel feed horn design and superior front-end components, this LNB provides higher conversion gain yet with low noise figure and best phase noise performance. The combination of innovative feed horn design, higher spec components, excellent cross polarization isolation and advanced filter design enables improved handling of interfering and spurious signals. This LNB provides a leap in the overall reception performance compared with standard LNBs, enabling the reception of signals from one satellite, its distribution to a single tuner Set-top box and is ready for Ultra High Definition TV transmissions in 4K or 8K resolution. Designed to meet strict specifications and manufactured to the highest industry standards, this unique range of LNBs is an ideal solution for installations with challenging reception conditions.
