Frequently Asked Questions

What is an ANTI-5G WR75 LNB?

The ST-K11G features matrix waveguide transmission with built-in anti-5G IMT @3.5GHz band interference capability, eliminating the need for external filtering components.

What is a Strong Rejection-5G WR75 LNB?

This WR75 LNB incorporates a built-in high-performance out-band rejection passive filter that provides strong immunity against 5G IMT@3.5GHz frequency interference. With guard band of 100MHz and handling power levels up to -30dBm, it maintains output gain stability without intermodulation or saturation.

What is High Gain Low Noise?

High Gain (63dB typical) enables reception of weak intensity signals, while Low Noise (0.8dB maximum) ensures optimal system C/N value for superior signal quality and reliability.

Advantages of Integrated 5G Rejection Technology

Superior Rejection Performance

> 110 dB rejection at 3.5GHz - far exceeds external filter solutions
No additional insertion loss in Ku-band (external filters typically add 0.3-0.8 dB)
Better system noise figure maintained

System Integration Benefits

No external components required
Reduced complexity in installation
No additional connections (eliminating potential PIM/failure points)
Weatherproof integrity maintained

Enhanced Reliability

Factory-tuned performance
No field alignment required
Consistent performance over temperature and time
