CPI LRK1XXX-XXXXXXX 1:1 Ku-Band Redundant LNA System

CPI CPI LRK1XXX-XXXXXXX  1:1 Ku-Band Redundant LNA System

The CPI LRK-1000 1:1 Ku-band redundant LNA system minimizes receiver downtime by automatically switching the RF path from the primary LNA to a dedicated standby LNA when a failure is detected. The system includes two CPI LK-12000 Series LNAs, an outdoor antenna-hub plate assembly, an indoor redundancy controller and an interconnecting control cable.
