Monoblock Quad LNBF ST-K242F - Dual Satellite LNB with 8 Outputs
The Ku-Band MONOBLOCK LNBF ST-K242F is a single housing unit containing two separate LNBs for receiving signals from two different satellites. Each LNB features four independent outputs (Quad capability), providing 8 total coaxial outputs for comprehensive satellite reception.
Product Overview
  • Physical Design: One unit with two integrated feedhorns
  • Satellite Coverage: Two specific orbital positions (e.g., Astra 19.2°E & Hotbird 13.0°E)
  • Total Outputs: 8 coaxial connections (4 from each satellite's LNB)
  • Primary Function: Enables multiple receivers to access both satellites simultaneously
Key Features
  • Input Frequency: 10.7~12.75 GHz
  • LO Frequencies: 9.75 GHz and 10.6 GHz
  • Polarization: Vertical and Horizontal
  • Satellite Reception: Two satellites with 4°~6° spacing

How a Monoblock Quad Works
A Monoblock LNB contains two independent LNBs in a single housing, allowing reception from two different satellites at slightly different orbital positions using a single dish. Satellite switching is achieved via DiSEqC signals.
Monoblock Quad Unit:
├── LNB #1 (e.g., Astra 19.2°E)
│ ├── Output 1: Tuner A, Satellite A
│ ├── Output 2: Tuner B, Satellite A
│ ├── Output 3: Tuner C, Satellite A
│ └── Output 4: Tuner D, Satellite A

└── LNB #2 (e.g., Hotbird 13.0°E)
├── Output 5: Tuner A, Satellite B
├── Output 6: Tuner B, Satellite B
├── Output 7: Tuner C, Satellite B
└── Output 8: Tuner D, Satellite B
Real-World Applications & Use Cases
Multi-TV Household with Diverse Needs
TV 1: German channels from Astra 19.2°E + Italian channels from Hotbird 13.0°E
TV 2: French channels from Astra + Arabic channels from Hotbird
TV 3 & 4: Same flexibility across the house
Benefit: Every TV can access both satellite clusters simultaneously
Recording/Watching Complex Scenarios
With a dual-tuner receiver (like a Twin Tuner PVR):
Simultaneous actions possible:
• Record two channels from Astra
• Watch one channel from Hotbird
• All operations can occur simultaneously!
Small Multi-Dwelling Unit
Ideal for apartments or duplex with 2-4 units where each apartment gets access to both satellite groups through a centralized dish installation, reducing infrastructure costs while maintaining full functionality.
