Q: What is an ANTI-5G WR75 LNB?
A: It's an LNB designed with a waveguide path that inherently rejects 3.5GHz-band 5G IMT interference. No external mechanical filter is needed – the high-performance out-band rejection filter is built-in.
Q: How is this different from a standard anti-5G LNB?
A: Many anti-5G LNBs only offer basic filtering. The WR75 goes further: even with strong 3.5GHz interference (-30dBm input), output gain shows no intermodulation and no saturation – the in-band signal remains perfectly linear. That's the key differentiator.
Q: What is the real-world benefit of "High Gain Low Noise"?
A: 63dB typical gain lets you receive very weak signals (long distances, rain fade). The 0.5dB typical noise figure ensures a superior Carrier-to-Noise ratio (C/N) . Together, they maximize link availability and stability.
Q: Can the LO frequency be customized?
A: Yes. The standard version supports multiple LO frequency options including 9.75 / 10 / 10.6 / 10.75 / 11.25 / 11.3 GHz. Other frequencies can be customized upon request.
Q: How effective is the lightning protection?
A: Built-in 4KV~6KV surge protection effectively withstands lightning-induced overvoltage, reducing equipment damage risk during storms – ideal for unattended outdoor installations.
Q: The input interface is WR75. What output interface options are available?
A: Output interface options include F-type (75Ω) and N-type (50Ω) – flexible selection based on your receiving equipment interface requirements.
