KU Band Quad LNB

High-Performance LNBs - High Gain, Low Noise

The KU Band Quad LNB is ideal for reliable satellite signal performance in both residential and professional setups. With ultra-low noise and a high-gain design, it delivers clear reception even in weak signal areas or extreme weather. This quad-output LNB is ideal for applications requiring multiple receivers, offering great performance and precision across the full KU band frequency range.

Built to withstand harsh outdoor conditions, it operates from -40°C to +70°C and features automatic switching between vertical and horizontal polarities. It also comes in the same colour as our satellite dishes for a consistent, professional appearance—and includes an LNB holder for quick and secure installation.

Features

• Ultra-low noise for clearer signal: 0.3 dB noise figure reduces signal loss and improves picture and sound quality.
• High gain boosts weak reception: 65 dB gain amplifies weak satellite signals without distortion.
• Quad output for multiple devices: Connects up to four receivers from one dish for multi-room use.
• Durable design for all climates: Weatherproof construction operates from -40°C to +70°C.
• Auto-switches polarity and band: Supports 22 kHz tone switching and voltage control for seamless operation.

Applications

Ideal for both domestic and commercial satellite installations, the KU Band Quad LNB is suited to:

• Satellite TV setups (including multi-room systems)
• IRS
• Installations demanding stable KU band performance
