LNB/LNA/BDC and BUC Redundant Switch Systems

Our low noise block downconverter (LNB), block downconverter (BDC), low noise  amplifier (LNA), and block upconverter (BUC) redundant systems are custom-made to your specifications. The outdoor unit can be modified for hub, boom, prime focus, rack and other mounting considerations – and the indoor controller is pre-mounted on a 1 RU 19-inch rail. Redundancy can be automatic (current sensing or external alarm) or manually selected. Power supply redundancy is automatic, and remote SNMP M&C via an Ethernet port is included.

If you need a custom redundancy system, please contact us and we’ll build one to your specifications. Alternatively, if you would like a smart, at-the-dish redundancy controller that can be operated remotely (no indoor unit required), please check out the Orbital iSwitch.
