The Inverto Dielectric Quad 23 mm LNB is a slim, high-performance Universal Quad LNB specifically designed for multifeed installations where several LNBs are mounted on the same satellite dish.
Its narrow feedhorn and extended neck allow multiple LNBs to be positioned close together. Depending on the size and design of the dish and the geographical installation location, this can enable reception of satellite positions spaced approximately 2 degrees apart.
Advanced dielectric materials, an optimised front-end design and slim-feed technology help provide efficient energy transfer from the satellite dish to the LNB, even when several units are positioned close together.
Four independent outputs can supply signals from one satellite to up to four satellite receivers or tuners. The LNB is also suitable for two Twin Tuner receivers, provided that every tuner is connected using a separate coaxial cable.

🔧 Use and Connection
The LNB is installed in a suitable 23 mm LNB holder or compatible multifeed bracket. Its extended neck provides additional adjustment range and makes it easier to position several LNBs close together.
Each receiver or tuner must be connected to a separate output using its own coaxial cable. To allow every connected tuner to select its required frequency band and polarisation independently, each tuner requires a direct cable connection to the LNB.
The ability to receive satellites spaced approximately 2 degrees apart depends on the dish diameter, multifeed bracket design, satellite positions and signal strength at the installation location.
