The Inverto Twin Flange LNB is a high-quality Universal Twin LNB for satellite dishes that use a separate feedhorn. It is particularly suitable for prime focus dishes and professional installations where the feedhorn is matched to the antenna design.
The LNB has two independent outputs and can be connected to two separate satellite receivers or one dual-tuner receiver. Each output can select its own polarisation and frequency band, supporting simultaneous viewing and recording.
With a specified 0.2 dB noise figure, minimum 55 dB conversion gain and good cross-polarisation isolation, the model provides stable reception of digital satellite television and HDTV.

🎯 Ideal For
- Prime focus satellite dishes
- Antennas using a separate feedhorn
- Two separate satellite receivers
- One receiver with two satellite tuners
- Simultaneous viewing and recording
- Professional satellite installations
- Replacing an existing Twin flange LNB
- Installations where a conventional 40 mm LNB cannot be used
🔧 Use and Connection
The LNB is mounted directly onto a compatible separate feedhorn. The feedhorn collects and guides the satellite signal reflected by the dish into the LNB.
Its two F-outputs are connected with separate 75-ohm coaxial cables to two receivers or to individual tuners in a compatible receiver. Each output operates independently and can select its own frequency band and polarisation.
Confirm the feedhorn’s flange type and mounting-hole pattern before installation. This is a flange LNB and cannot be installed directly in a conventional 40 mm LNB holder.
