CORAB C120TWN Twin LNB Converter – 2 Outputs, 40mm Feedhorn, Low Noise 0.1 dB, Weatherproof F-Type

The CORAB C120TWN Twin LNB converter stands out with its dual output design, enabling two independent receivers to operate from a single satellite dish without signal loss. Unlike single-output LNBs that force compromises, this twin model delivers consistent 55–65 dB conversion gain across the entire Ku-band, making it ideal for multi-room setups or PVR systems. The 40 mm feedhorn with sliding weather cover ensures reliable performance in harsh outdoor conditions, while the low 0.1 dB noise figure preserves weak signal integrity.

Highlights

• Twin LNB with 2 independent F-type outputs
• Wide input range 10.7–12.75 GHz, output 950–2150 MHz
• Low noise figure: 0.1 dB typical
• High conversion gain: 55–65 dB
• Universal LO switching: 9.75 / 10.6 GHz
• Weather-resistant housing with sliding cover
• Linear polarization (H/V) with >20 dB isolation
• Operating temperature -30°C to +60°C

In daily use

Installation is straightforward thanks to the standard 40 mm feedhorn clamp and clear polarization markings. The twin outputs let you feed a main TV and a secondary receiver or a PVR with dual tuners, eliminating the need for a multiswitch in small installations. The low power consumption (max 120 mA) reduces strain on the receiver's LNB power supply, while the ±0.5 dB gain flatness over 26 MHz ensures stable signal across all transponders. The sliding weather cover protects the F-connectors from rain and dust, extending service life.
