Ku-Band MONOBLOCK LNBF ST-K242F

A Monoblock Quad is a single housing unit containing two separate LNBs (for receiving two different satellites), with each LNB having four independent outputs (Quad capability), resulting in 8 total coaxial outputs.

Physical: One unit with two feedhorns
Satellite Coverage: Two specific orbital positions (e.g., Astra 19.2°E & Hotbird 13.0°E)
Total Outputs: 8 (4 from each satellite's LNB)
Function: Allows multiple receivers simultaneous access to both satellites

Key Features

Input: 10.7~12.75 GHz
LO: 9.75 GHz and 10.6 GHz
Polarization: Vertical and Horizontal
Receive: Two Satellite (4°~6°)

Frequently Asked Questions

What is a Monoblock LNB?

This design consists of two independent LNBs in a single housing and allows a user the potential of receiving the signal from two different satellites which are at slightly different orbital opposition from a single dish installation. The switching between the satellites is achieved via the use of DiSEqC signals. Monoblock LNB's are available mostly for satellites with a fixed 2°/ 3°/4.3° or 6° spacing and the range covers Ku band Monoblock switch single, twin and quad outputs. For, example where a 2°Monoblock LNB could be used is for the reception of 5°W and 7° W or with 3° distance for the reception of 13° E and 16° E.

How a Monoblock Quad Works

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

1. 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

2. 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 at the same time!

3. Small Multi-Dwelling Unit

Apartments or duplex with 2-4 units
Each apartment gets access to both satellite groups
Centralized dish installation
