CPI BRK1100.1134 1:1 Ku-Band Redundant LNB System

CPI BRK1100.1134 1:1 Ku-Band Redundant LNB System

The CPI BRK1100.1134 is a 1:1 Ku-band redundant LNB system designed to minimize receiver downtime by automatically switching from the primary LNB to a dedicated standby LNB when a failure is detected. Using dual-output PLL LNBs, the system simultaneously provides low-band and high-band outputs for full 10.70–12.75 GHz Ku-band coverage. It 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.
