Satellite LNB Corab CORAB C120TWN Twin Konwerter

Corab CORAB C120TWN Twin Konwerter is a satellite low-noise block converter (LNB) designed to receive and convert satellite microwave signals for two independent tuners or receivers. The twin-output design allows simultaneous connection of two receivers or a dual-tuner PVR to a single dish feed, maintaining stable signal conversion for home television and small-scale installations.

Advantages

The twin LNB provides two separate, isolated outputs so two tuners can access the satellite signal without additional multiswitch equipment. Low-noise characteristics improve reception quality, while the device’s form factor is compatible with standard offset satellite dishes. The unit supports typical Ku-band satellite reception and is built for straightforward mounting and weather exposure typical for rooftop or pole installations.

Suitable for

• Home satellite TV with two receivers
• Dual-tuner PVR installations
• Small apartments or houses requiring two independent satellite feeds
• Simple two-user shared satellite setups without a multiswitch

Key specifications

• Configuration: Twin-output LNB (two independent outputs)
• Frequency band: Ku-band satellite reception (standard L-band downconversion)
• Noise performance: Low-noise design for improved signal-to-noise ratio
• Outputs: Two F-type compatible outputs for direct connection to receivers
• Mounting: Standard clamp or feed-arm mount for common offset dishes
• Environmental resistance: Weatherproof housing for outdoor use

How to use

Install the twin LNB on the dish feed arm according to the dish manufacturer’s alignment instructions. Connect each output using coaxial cable to the respective satellite receiver or to the two tuner inputs of a dual-tuner PVR. Configure each receiver to the satellite parameters and perform a signal scan; adjust dish alignment if required to maximize signal strength and quality. Ensure proper grounding of the satellite system and use connectors tightened to manufacturer torque recommendations to prevent water ingress.

Usage recommendations

Use quality coaxial cable and weatherproof F-type connectors to maintain signal integrity. Regularly inspect connectors and seals for corrosion or water ingress, and recheck dish alignment after strong winds or maintenance. For systems expanding beyond two tuners, combine this twin LNB with an appropriate multiswitch or replace with a multi-output LNB suited to the installation size.
