An LNB (Low Noise Block, also called LNC - Low Noise Converter) is used for broadcast satellite reception. The LNB is mounted on the satellite dish to collect and amplify the satellite signal, then downconvert it to a more manageable IF frequency that can be carried over standard coaxial cabling to the receiver. Available in C-Band, Ku-Band, and Ka-Band versions for different frequencies.
The feedhorn is part of the LNB that works like a directional horn. It captures signals reflected from the dish while shielding the LNB from extraneous radiation. These collected signals are then passed to the electronics within the LNB. Available in orthogonal feed, offset feed, and elliptical feed configurations.
This design features two independent LNBs in a single housing, allowing reception from two different satellites at slightly different orbital positions using a single dish. Switching between satellites is achieved via DiSEqC signals. Monoblock LNBs are available mostly for satellites with fixed 2°/3°/4.3° or 6° spacing, covering Ku band with single, twin, and quad outputs.
An LNB that can connect multiple set-top boxes (STBs) using one RG6 cable. This energy-saving, multi-user receiving mode is sometimes called a stack LNB.
Unicable is a new method for distributing satellite television to multiple receivers (currently up to 32 according to standards EN 50494 & EN 50607).
Unicable 1: SCR LNB that only achieves static working model.
Unicable 2: Achieves both static and dynamic working models, with LNB designed for Universal+Unicable input separately (e.g., 1 output Universal + 1 output Unicable).
