The MTI Unicable dCSS 24CH LNBF is a modern LNB for satellite installations where several compatible receivers or tuners share the same coaxial network. It provides 24 preconfigured user bands and supports both EN50494 and EN50607.
Unicable technology allows up to 24 compatible tuners to be assigned individual user bands. Signals can be distributed through one coaxial cable and suitable satellite splitters, simplifying the installation and reducing the need for a separate cable from the dish to every tuner.
According to the specified test results, the LNB provides consistent signal levels across its user bands, with approximately 2 dB variation between the strongest and weakest band. Its 60–70 dB gain and typical 0.7 dB noise figure make it suitable for modern multiroom and FBC installations.

🔧 Installation and Configuration
Connect the LNB output to compatible receivers using coaxial cable and satellite-rated splitters with DC and DiSEqC pass-through.
Every tuner must be assigned a unique user band and the correct frequency. The same user band must not be assigned to two tuners within the same system, as this will cause control and signal conflicts.
User bands 1–8 can be used with compatible EN50494 or EN50607 equipment. User bands 9–24 require EN50607 support.
Before installation, confirm that all receivers, tuners and satellite splitters are compatible with the Unicable system.
