The Opticum SCR 4UB + 3 Legacy is a hybrid Unicable (SCR) LNB combining a single-cable output for up to four Unicable/SCR receivers with three additional full-band outputs for traditional digital receivers — all from one LNB on one dish. The gold-coloured SCR output distributes signals to up to four Unicable-compatible receivers simultaneously over a single coax cable, using four fixed IF frequencies (1210, 1420, 1680, and 2040 MHz). Each receiver operates fully independently. The three silver full-band outputs provide standard satellite IF for conventional receivers or set-top boxes without Unicable support. Note: Unicable receivers must support the SCR/Unicable function to use the single-cable output. Key Features 1 SCR/Unicable output — up to 4 independent Unicable receivers on one cable SCR IF frequencies: 1210 / 1420 / 1680 / 2040 MHz 3 full-band outputs for traditional digital receivers Input: 10.7–11.7 GHz (LO: 9.75 GHz) and 11.7–12.75 GHz (LO: 10.6 GHz) Noise figure: 0.1 dB | Gain: >57 dB Current consumption: 300mA Handle diameter: 40mm Operating temperature: −40°C to +65°C Ideal For Single-cable satellite installations (flats, apartments) Mixed installations with Unicable and legacy receivers Sky Q, Freesat, and SCR-compatible satellite systems
