Frequently Asked Questions
What is an LNB?
An LNB (Low Noise Block, also called an LNC - Low Noise Converter) is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish and its purpose is to collect and amplify the satellite signal received from the dish and then down convert the signal to lower more manageable IF frequency which can then be carried over standard coaxial cabling to the receiver. Divided into C-Band, Ku-Band, Ka-Band according to different frequency.
What is a feedhorn?
The feedhorn is a part of the LNB and works like a directional horn. Its function is to capture the signals reflected from the dish and to shield the LNB from receiving extraneous radiation from other sources. These collected signals are then passed from the horn to the electronics within the LNB. Divided into Orthogonal feed, offset feed and elliptical feed.
What is a Monoblock LNB?
This design consists of two independent LNBs in a single housing and allows a user the potential of receiving the signal from two different satellites which are at slightly different orbital opposition from a single dish installation. The switching between the satellites is achieved via the use of DiSEqC signals. Monoblock LNB's are available mostly for satellites with a fixed 2°/3°/4.3° or 6° spacing and the range covers Ku band Monoblock switch single, twin and quad outputs.
What is a one cable solution LNB?
LNB can connect multi-STB (set-top-box) by one RG6 cable, is a saving energy and multi-users receiving mode, sometimes also called stack LNB.
What does Unicable mean?
Unicable is a new method for distributing satellite television. Several receivers (currently up to 32 in accordance with standard EN 50494 & EN 50607). Unicable 1: It means SCR LNB, only achieving static working model. Unicable 2: Both achieving two working models with static and dynamic, LNB can be designed to achieve Universal+Unicable input separately.
