Frequently Asked Questions

What is an Anti-5G LNBF and why is it important?

An Anti-5G LNBF includes advanced filtering technology that blocks interference from 5G terrestrial networks operating in the 3.4-3.8 GHz range. This is critical because 5G signals can overload and damage standard C-band LNBs, disrupting satellite TV and data reception. Seton's Anti-5G LNBFs protect your satellite system with proprietary filtering while maintaining high signal sensitivity.

What is the difference between Universal and Single LO LNB?

A Universal LNB automatically switches between low band (10.7-11.7 GHz) and high band (11.7-12.75 GHz) using a 22 kHz tone from the receiver. It also supports vertical/horizontal polarization via voltage switching (13V/18V). A Single LO LNB operates on a fixed frequency range and is typically used in professional or fixed-band applications where automatic switching is not required.

Can Seton provide OEM/ODM services?

Yes, Chenzhou Seton Technology is a trusted OEM/ODM manufacturer with full R&D, production, and quality control capabilities. We offer custom branding, packaging, specifications, and engineering support for partners worldwide. Our factory has an annual capacity of 15 million LNB units with strict ISO-level quality processes.

What are the key advantages of Seton's LNBs?

Seton LNBs offer high reliability, low noise figures, excellent phase stability, and robust construction. Our Anti-5G models feature patented filtering technology. All products undergo rigorous testing and are designed for 24/7 operation in harsh environments. With 20+ years of microwave engineering expertise, we deliver cost-effective performance for global markets.
