LNB (Low-Noise Block) is a device that is used to receive satellite television signals. It is mounted on the satellite dish and is responsible for collecting the signal and sending it to the satellite receiver for processing. The LNB is an essential component of any satellite TV system.
Types of LNBs
There are different types of LNBs available in the market. Some of the common types are:
Single LNB - A single LNB is designed to receive signals from one satellite at a time.
Dual LNB - A dual LNB can receive signals from two different satellites simultaneously.
Quad LNB - A quad LNB can receive signals from four different satellites at the same time.
Octo LNB - An octo LNB can receive signals from eight different satellites at the same time.
Monoblock LNB - A monoblock LNB is designed to receive signals from two different satellites that are positioned close to each other.
Wideband LNB - A wideband LNB is capable of receiving signals from multiple satellites across a wide frequency range.
How does an LNB work?
The LNB is a small device that is attached to the end of the arm of the satellite dish. It works by collecting the satellite signals that are reflected off the dish and focusing them onto a small antenna. The antenna then converts the high-frequency satellite signals into lower frequency signals that can be transmitted through a coaxial cable to the satellite receiver.
The LNB also amplifies the signals it receives to ensure that they are strong enough to be processed by the receiver. The amount of amplification that is applied to the signal is called the gain. The gain of an LNB is typically measured in decibels (dB).
