CPI BRK1200.1136 1:2 Ku-Band Redundant LNB System

CPI BRK1200.1136 1:2 Ku-Band Redundant LNB System

The CPI BRK1200.1136 is a 1:2 Ku-band redundant LNB system that protects two independent receiver or polarization paths with one shared standby LNB. If either primary LNB fails, the controller automatically transfers the affected RF path to the standby unit. Dual-output PLL LNBs provide simultaneous low- and high-band outputs for full 10.70–12.75 GHz Ku-band coverage. The system includes an outdoor antenna-hub plate assembly, an indoor redundancy controller and an interconnecting control cable. Compatible Swedish Microwave dual-output PLL LNBs are ordered separately.
