Ku-Band Monoblock LNBF ST-K212F - Dual Satellite LNB with 4°~6° Spacing, 0.7dB

For users who need to receive programs from two adjacent satellites simultaneously, traditional solutions require two separate dishes or complex switching systems – high cost, large space occupation, and complicated installation. The Ku-Band Monoblock LNBF ST-K212F is exactly the solution.

This product integrates two independent LNBs into a single housing, allowing reception from two satellites with 4°~6° orbital spacing using just one dish. Built-in DiSEqC switching enables seamless switching between satellites. It supports full Ku-band coverage (10.7~12.75GHz) with automatic low/high band switching via 22KHz signal, compatible with all Ku-band satellite programs.

Challenge	How This LNBF Solves It
Need to receive two different satellites – no space for two dishes	One dish + Monoblock LNBF = simultaneous dual-satellite reception – saves 50% installation space.
Installing two dishes is expensive – limited budget	Single dish + single coaxial cable receives two satellites – significantly reduces equipment and installation costs.
Switching between two satellites is inconvenient	Built-in DiSEqC switching – receiver automatically controls satellite selection. Seamless user experience.
Different satellite spacing – compatibility concerns	Supports 4°~6° spacing – compatible with mainstream satellite combinations (e.g., Hotbird + Astra).
Weak signal environments – poor picture quality	Noise figure as low as 0.7dB (Typ.) – excellent weak signal reception for clear picture quality.
Outdoor installation – rain ingress damage concern	O-ring sealed waterproof design – effectively prevents rain ingress for long-term outdoor installation.

Q: What is a Monoblock LNBF?

A: A Monoblock LNBF integrates two independent LNBs into a single housing, allowing reception from two satellites at slightly different orbital positions using one dish. Switching between satellites is achieved via DiSEqC signals. They are commonly available for fixed spacings of 2°/3°/4.3°/6° in Ku-band, with single, twin, and quad output options.

Q: What satellite spacing does this product support?

A: Supports 4°~6° satellite spacing. This is the typical spacing range for mainstream satellite combinations in European and Asian markets – such as the 6° spacing between Hotbird (13°E) and Astra (19.2°E).

Q: Does installing a Monoblock LNBF require special setup?

A: The installation process is similar to standard LNBs, but requires aiming the dish at the midpoint between the two satellites so each LNB aligns with its respective satellite. The receiver must support DiSEqC 1.0 or above for satellite switching.

Q: Will signals from two satellites interfere with each other when using one dish?

A: No. The two LNBs are physically oriented toward different satellites with built-in isolation ≥20dB, ensuring no signal interference between the two paths.

Q: What are the advantages of Monoblock over the traditional dual-dish solution?

A: The Monoblock solution requires only one dish and one cable to receive two satellites – saving 50% installation space and cost, cutting installation time in half, and simplifying maintenance.

Q: What is the real-world benefit of the 0.7dB noise figure?

A: Lower noise figure means the LNB generates less self-noise. With 0.7dB (Typ.) , you get clear, pixelation-free pictures even in weak signal environments – such as remote areas, light rain fade, or when using smaller dish antennas.

Q: What is the operating temperature range?

A: -30℃ to +60℃ – suitable for most climate conditions, from cold winters to hot summers.

Q: How effective is the waterproofing?

A: The O-ring sealed design effectively prevents rain and moisture from entering the LNB housing, making it suitable for long-term outdoor installation.
