- Description
- A Low-Noise Block Converter (LNB) is a crucial component in satellite communication systems. Its primary function is to receive high-frequency satellite signals (typically in the GHz range), amplify these signals, and convert them to a lower frequency for further processing. Typically, C band, X band and Ku band signals are down converted to L band which can be taken through coaxial cable to the receive subsystem components. While both LNB and LNA play important roles in satellite communication and RF systems, they serve distinct functions within the signal processing chain. LNB focuses on capturing and down converting satellite signals, reducing noise in the process, while LNA specializes in amplifying weak signals with minimal noise introduction. In a redundant system, if the primary LNB fails or experiences an issue, the secondary LNB automatically takes over. This ensures there is no interruption in the signal processing. A 1:1 system provides one spare LNB for one primary LNB. A 1:2 system provides a spare LNB for either of two primary LNBs. The systems consist of an outdoor plate assembly which mounts at the antenna hub, an indoor control panel and interconnecting control cable. The failover process is controlled by an automatic switching mechanism or monitoring system that detects a failure in the active LNB and switches to the backup without any manual intervention.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, Reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)) GIR 1 has been used to classify this product by the terms of heading 8543 - Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter GIR 6 - has been used to classify the goods to subheading level 854370 - Other machines and apparatus 8 Digit Code 85437030 - Aerial Amplifier Also Classified in Accordance with: Harmonized System Explanatory Notes (HSENs) (9) to Heading 8543
