CPI BRC-1100 1:1 C-Band Redundant LNB System

CPI BRC-1100 1:1 C-Band Redundant LNB System

The CPI BRC-1000 1:1 C-band redundant LNB system minimizes receiver downtime by automatically switching from the primary LNB to a dedicated standby LNB when a failure is detected. Covering 3.40–4.20 GHz with a 950–1750 MHz L-band output, the system includes an outdoor antenna-hub plate assembly, indoor redundancy controller and interconnecting control cable. Compatible Norsat C-band LNBs are selected and ordered separately.
