A Direct-to-Home (DTH) LNB (Low Noise Block) is a crucial device used in satellite television systems. It receives signals from satellites via a parabolic dish and converts them into lower-frequency signals that can be transmitted through coaxial cables to a satellite receiver. The LNB amplifies these signals and ensures minimal noise interference, enabling clear TV reception. Most LNBs are designed for specific frequency bands, such as Ku-band or C-band, depending on the satellite service provider. Modern LNBs, like universal or twin LNBs, support multiple connections for multiple receivers, making them versatile for household or commercial use. Proper alignment ensures optimal performance.
