The PLN type LNBF provides a better speed than the DRO type LNBFs. Typical temperature 15K. Stability +/- 50Khz. Frequency 3.4 ~ 4.2GHz. High FEC and narrow bandwidth satellite transponders. PLL Phase Lock Loop C-band LNBF is developed using the latest pll chipsets with a balance of gain, isolation, stability and amplification to produce a phase look loop C-Band LNBF that outperforms all other C-Band LNBFs
