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.
Frequently Asked Questions
How do I determine which spacing Monoblock I need?
First identify the orbital positions of the two satellites you want to receive (e.g., Astra 19.2°E and Hotbird 13.0°E). Calculate the difference in longitude: 19.2 - 13.0 = 6.2°, so you need the 6° spacing model. Calculate similarly for other combinations.
Do I need to connect all 8 output ports?
No. You can connect only the ports you need based on your requirements. We recommend using the included dust caps on unused ports to prevent oxidation and water ingress.
Can I record programs from both satellites simultaneously with one dual-tuner receiver?
Yes. Connect the receiver's Tuner A to any Sat A output port, and Tuner B to any Sat B output port. After correctly configuring both satellites in the receiver settings, you can simultaneously record programs from both satellites, or record from one while watching the other.
How waterproof is the product? Can it be used in rainy areas?
This product has IP65 waterproof rating, with O-ring seal design, fully rainproof and splash-proof. The housing is made of UV-resistant engineering plastic, won't age or crack during long-term outdoor use. Suitable for all climate conditions, including rainy and humid areas.
Is the signal strength consistent across all 8 output ports?
Yes. The internal circuit design of each LNB ensures uniform signal distribution across the 4 output ports, with gain variation controlled within ±1dB. You'll get consistent signal quality regardless of which port you connect.
Customer Testimonials
"I've been running a satellite installation company for 15 years, handling countless LNBs. This Monoblock Quad is one of the best products I've ever seen. The 8 output ports perfectly solve distribution needs for large apartment buildings, signal quality is stable, zero complaints from clients. Highly recommended to fellow installers!"
— Hans Mueller, Berlin
"Our family of 5 needed TV in 4 rooms. Previously used two dishes with switches, constant problems. After switching to Monoblock Quad, everything became simple! Living room, master bedroom, both kids' rooms, even the kitchen can all watch different satellite channels simultaneously, no more fighting over remotes. Installation was easy, I did it myself."
— David Thompson, London
"I manage a small apartment building with 8 units. Previously each unit had their own dish, the roof looked like a spider web. Now with Monoblock Quad, one dish solves all problems! Each unit can independently receive Astra and Hotbird programs, signal quality is even better than their small individual dishes. The roof is tidy, residents are satisfied, and I'm worry-free."
— Pierre Dubois, Paris
