One Cable Solution Anti-5G C-Band PLL LNB with Strong 3.5GHz Rejection Ultra-Low Noise 17°K and 60dB Conversion Gain

With the rapid deployment of 5G networks, spectrum interference in the 3.5GHz band has become a critical challenge for satellite reception. The One Cable Solution Anti-5G C-Band PLL LNB is specifically engineered to overcome this challenge, delivering superior satellite signal performance even in harsh 5G environments.

This product integrates two core technologies:

• Strong 5G Interference Rejection – Built-in high-performance filtering withstands 5G interference up to -30dBm in the 3.3~3.6GHz band

• One Cable Solution (Stacked LNB) Technology – A single RG6 coaxial cable connects multiple set-top boxes, dramatically reducing cabling costs

It is the ideal upgrade from traditional stacked LNBs, especially for Multi-Dwelling Units (MDUs), hotels, apartments, and complex electromagnetic environments.

One cable, multiple users. Rock-solid signal, even with 5G interference.

Challenge	How This LNB Solves It
Nearby 5G base stations cause signal dropouts or poor quality	Built-in high-performance 5G filtering withstands -30dBm interference – no intermodulation, no saturation. In-band signal remains pure.
MDU/Apartment/Hotel – complex, costly cabling for multiple users	One Cable (Stacked) Technology – single RG6 cable connects multiple STBs. Dramatically reduces cabling cost and installation time.
Weak signals cause pixelation and dropouts	Ultra-low noise temperature (17°K Typ. ) easily captures weak satellite signals, ensuring clear picture quality.
Extreme outdoor temperatures cause frequency drift and signal loss	PLL technology delivers only ±0.75MHz drift (-30℃~+60℃) – stable lock in scorching heat or freezing winter.
Multi-cable systems suffer high signal loss and power consumption	One Cable architecture minimizes signal loss and reduces overall system power consumption.

Q: What is "One Cable Solution (Stacked LNB)" technology?

A: One Cable Solution (Stacked LNB) technology allows a single RG6 coaxial cable to carry multiple frequency bands simultaneously, connecting multiple set-top boxes. It dramatically reduces cabling quantity, installation cost, and signal loss – the ideal choice for multi-user environments.

Q: How is this LNB different from a standard anti-5G LNB?

A: In addition to strong 5G interference rejection, this product integrates One Cable Solution technology. A standard anti-5G LNB typically serves only one receiver, while this product serves multiple users over a single cable – all while maintaining ultra-low noise (17°K) and high gain.

Q: What is the real-world benefit of 17°K noise temperature?

A: Lower noise temperature means the LNB generates less self-noise, allowing it to capture weaker satellite signals. With 17°K Typ. , you get clear, stable pictures even in remote areas, light rain fade, or when using smaller dish antennas.

Q: Is the ±0.75MHz temperature drift specification important?

A: Very important. LNBs are typically installed outdoors and experience extreme temperatures. ±0.75MHz drift means the LO frequency remains highly stable from -30℃ to +60℃ – your demodulator will not lose lock due to weather changes.

Q: Can the input and output frequencies be customized?

A: Yes. The standard version covers 3.7~4.2GHz input with 950~1450MHz & 1550~2050MHz output. We offer customizable frequency plans to match different regional and project-specific band requirements.
