High Gain C Band LNB

High Gain C Band LNB

The LNB gets its power from the receiver or set-top box, using the same coaxial cable that carries signals from the LNB to the receiver.

Product Feature

This High Gain C Band LNB is actually the heart of the antenna. It is mainly a resonance chamber for receiving signals that are reflected by the antenna surface and then processed. Additional circuitry amplifies these electrical signals before they are routed into the cable and converts them to lower frequencies in order to reduce signal loss during cable transmission.


Product Description

This High Gain C Band LNB is a new kind of low noise down converter. Its function is to amplify and downconvert the satellite signal transmitted by the feed, and turn the Ku or C band signal into L band, via coaxial cable. Because the satellite signal is quite weak before reaching the antenna and the higher the frequency of coaxial cable transmission, the signal loss is larger, so the LNB is needed to amplify, and the signal-to-noise ratio cannot be deteriorated too much. Equipped with advanced process, our High Gain C Band LNB's workflow is to first amplify the satellite high-frequency signal, and then use the local oscillator circuit to convert the high-frequency signal to the intermediate frequency again to facilitate the transmission of coaxial cable and satellite. It is like a section of a pipe that converts the energy of a radio wave into an electrical signal via a polar probe.
