SETON’s High-Performance C-Band LNB Enables Stable Multi-Channel Reception for National Broadcaster

A national broadcasting agency in Southeast Asia sought to upgrade its satellite reception system to support more simultaneous channels and improve signal stability. The existing equipment struggled with performance in high-temperature, high-humidity environments and suffered significant signal degradation due to 5G interference—resulting in frequent disruptions to broadcast quality.

The client required a robust LNB solution with strong anti-interference capabilities to ensure uninterrupted, high-definition program transmission.

• High channel volume and wide frequency coverage required sensitive C-band reception
• Tropical climate demanded corrosion-resistant and heat-tolerant hardware
• Severe 5G interference disrupted signal integrity
• Compatibility with existing infrastructure was essential to avoid costly system overhauls

SETON delivered a C-band anti-5G interference LNB solution, leveraging over 20 years of experience in microwave communication. Key features included:

• Anti-5G Interference Design: Proprietary filtering structure effectively blocks disruptive 5G signals.
• High Sensitivity Reception: Optimized low-noise amplifier for improved weak signal capture.
• Industrial-Grade Durability: Waterproof and corrosion-resistant housing for tropical climates.
• Modular Interface: Fast deployment and seamless integration with existing systems.
• Mass Production Capability: With an annual output of 15 million LNBs, SETON ensures reliable supply for large-scale projects.
• SETON’s technical team supported remote calibration and system alignment throughout deployment.

• Signal strength improved by 42%, significantly enhancing broadcast stability.
• Client feedback: “The system remains stable even during heavy rain and extreme heat—far beyond expectations”.
• Bit error rate reduced to below 0.1%, meeting HD transmission standards.
• Maintenance frequency dropped, cutting operational costs by approximately 30%.

This solution has been successfully adopted by multiple national broadcasters and is ideal for:

• Ground satellite reception stations
• Mobile broadcast vehicles
• Emergency broadcast platforms
• Multi-channel synchronization systems
