The Low Noise Block Down Converter LNB-KuDxx v1 is designed for gaining and transforming the RF signals from Ku-band to L-band intermediate frequencies. This block has a waterproof case and can be mounted in close proximity to the antenna. LNB's parameters correspond to MVDS/MITRIS TV broadcasting systems requirements and are fully compatible with DVB-S/S2 or DVB-C standards. LNB can operate up to 25 carriers. LNB-KuDxx v1 has PBR120 input flange and can be used with regular RRL or recieving antennas.

This LNB can be supplied with next frequency values of the Local Oscillator:
