LNB from Probecom is specially sourced for their TVRO antenna. Various style and design greatly meet different requirements from clients.

LNB stands for low-noise block down converter, is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish. Also called a low-noise block, LNC (for low-noise converter), or even LND (for low-noise down converter), the device is sometimes wrongly called an LNA (low-noise amplifier).

The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and IF amplifier. It receives the microwave signal from the satellite collected by the dish, amplifies it, and downconverts the block of frequencies to a lower block of intermediate frequencies (IF). This downconversion allows the signal to be carried to the indoor satellite TV receiver using relatively cheap coaxial cable; if the signal remained at its original microwave frequency it would require an expensive and impractical waveguide line.
