The Inverto Dielectric Twin 23 mm LNB is specifically designed for multifeed installations where several LNBs need to be positioned closely together on the same satellite dish.
Its advanced Slim Feed technology uses dielectric materials and an optimised front-end design to provide efficient signal transfer from the dish to the LNB. The slim, extended mounting neck allows precise positioning when satellite orbital locations are close together.
The LNB features two independent outputs and can supply signals from one satellite to two separate receivers or one receiver equipped with two tuners. Each connected tuner can independently select its frequency band and polarisation.
With a typical noise figure of 0.2 dB, a minimum conversion gain of 60 dB and support for DVB-S2 and HDTV, this is a stable and energy-efficient solution for advanced multifeed systems.

🔧 Use and Connection
The Inverto Dielectric Twin LNB is installed in a suitable 23 mm LNB or multifeed holder. Its long, slim neck makes it easier to position several LNBs close together and precisely align them with their respective satellite positions.
The two outputs are connected using separate coaxial cables to two receivers or both inputs on a dual-tuner receiver. Each tuner can then independently control its frequency band and polarisation.
The achievable spacing between satellite positions depends on the dish size, focal length, multifeed holder, geographical location and LNB positioning.
