SK1312

Core Specifications

• Inputs: 12 satellite IF inputs (four satellite positions × three LNBs) + 1 terrestrial (VHF/UHF) antenna input → 13 inputs total

• Outputs: 12 subscriber ports 

• Frequency Range:

  • Satellite: 950–2150 MHz

  • Terrestrial: 47–862 MHz 

⚙️ Signal Performance

• Amplified SAT path: Low insertion loss, delivering up to ~100 dBµV to subscribers (IMA‑3 / EN50083‑3) 

• High isolation:

  • Satellite ↔ terrestrial: ≈25–28 dB

  • Between satellite polarities and LNBs: ≥30–35 dB 

• Build quality: Shielded metal chassis with F‑type connectors; engineered for indoor installation 

🔌 Power & Control

• Powering: SAT paths amplified; some models require power via receivers, others use external PSU (~18 V/2.5 A) 

• Cascadable: Designed for large-scale systems—can be cascaded with identical units and amplifiers to serve up to 64+ outputs 

• DiSEqC controlled: SAT inputs switch automatically via standard receiver commands (13/18 V plus 22 kHz tone) 

✅ Ideal Applications

• Perfect for medium-to-large installations: apartment blocks, small hotels, communal TV systems

• Designed to distribute satellite + terrestrial signals over a robust coax network

• Reliable, scalable solution thanks to cascade-friendly design
