C-band LNB PLL LO 5.15 is Low Noise Block Down Converter which is designed for RF signals gaining and transforming from C-band to L-band (intermediate frequencies). The LNB PLL LO 5.15 has a waterproof case. LNB PLL LO 5.15 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 5.15 has input flange of CPR-229G type and can be used with regular RRL or receive antennas.
