PLL (Phase Locked Loop) LNBs are typically only found in high end commercial systems and historically cost 10, 20 or even 30 times or more than the LNBFs produced for the residential customers. The C1 Phase Lock Loop is a breakthrough LNBF, built with the highest grade materials and the latest RDA chipset and PCB technology. Recent technology allow for cost effective production of PLL LNBFs with lower current draws, lower heat generation, lower internal noise generation and increased performance. The GEOSATpro C1 Phase Lock Loop has been designed to meet the requirements for commercial applications and the most demanding satellite hobbyist. Reliable reception of digital S2 HD MPEG4 channels with low symbol rates or high FEC requires an LNBF that excels in several performance benchmarks. The C1 Phase Lock Loop has exceptional flat gain across the 3.7 - 4.2GHz frequency range, features an excellent phase noise rating with low internal noise generation during signal conversion / amplification and stable frequency tuning for narrow bandwidth signals.Regular LNBFs are designed to last only five to seven years. Slowly, a typical DRO LNBF loses performance as the mechanically tuned frequencies slowly drift until one day the receiver is no longer capable of tuning the satellite channels. PLL LNBFs do not rely on a mechanical tuning slug that may shift off frequency due to physical damage or aging. PLL LNBFs have an internal crystal oscillator that will remain tuned exactly on frequency even in the harshest the environmental conditions.
