The Invacom TWF-031 is a professional Twin LNB with a C120 flange, designed for satellite systems where stable reception, low noise and excellent signal quality are particularly important.
Its two independent outputs allow two satellite receivers or two separate tuners to be connected directly. Each receiver or tuner can select its frequency band and polarisation independently without affecting the other connection.
The typical noise figure of only 0.3 dB and gain of 50–60 dB make this model particularly suitable for demanding installations and locations with weaker satellite signals. Its precision construction helps provide low phase noise, excellent isolation and very low spurious signal levels.
The TWF-031 features a C120 flange connection and is used with a separate compatible feedhorn. This allows the installer to select a feedhorn suited to the design and characteristics of the satellite dish.

🔧 Use and Connection
The Invacom TWF-031 is installed on a separate feedhorn with a compatible C120 connection. Its two LNB outputs are connected using separate coaxial cables to two satellite receivers or to both tuner inputs on the same receiver.
Each connected tuner can control the polarisation and frequency band independently. This allows one satellite channel to be watched while another is recorded, provided the receiver has two tuners and two separate antenna cables.
This is a C120 flange LNB and not a conventional Universal LNB with a 40 mm mounting neck. A compatible feedhorn is required for installation.
