  • Description
  • Downloads

LNB PLL LO 9.75 is Low Noise Block Down Converter which is designed for RF signals gaining and transforming from Ku-band to L-band (intermediate frequencies). The LNB PLL LO 9.75 has a waterproof case. LNB PLL LO 9.75 can be mounted in close proximity to antenna. LNB parameters correspond to MVDS / MITRIS TV broadcasting systems conditions in accordance with DVB-S/S2 or DVB-C standard and can be operated up to 25 carriers. LNB PLL LO 9.75 has input flange of PBR120 type and can be used with regular RRL or receive antennas.
