A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.
The set-top box selects the channel desired by the user by filtering that channel from the multiple channels received from the satellite, converts the signal to a lower intermediate frequency, decrypts the encrypted signal, demodulates the radio signal and sends the resulting video signal to the television through a cable.

Two monoblock LNB can be connected to one receiving dish using Multi-satellite techniques. However, the expected results of such connections may vary or be sub-optimal. The results may yield low-level signals from some or all of the satellites or it may work well in certain geographically favorable locations.
A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit .
By combining satellite reception and IP bridging at the dish, the IP-LNB enables satellite content distribution to the home over a single Ethernet cable, which carries both the IP TV and power for the LNB through Power over Ethernet (PoE) technology, reducing the overall system cost and power consumption. As of July 2012, the prototype IP-LNB ...
Unicable. Single-cable distribution is a satellite TV technology that enables the delivery of broadcast programming to multiple users over a single coaxial cable, and eliminates the numerous cables required to support consumer electronics devices such as twin-tuner digital video recorders (DVRs) and high-end receivers.
Provided that the LNB has sufficient outputs, a single dish may be used to receive multiple services (i.e. Sky and Freesat). However, a dish with an LNB for the Sky Q service cannot be used with most types of Freesat receivers because Sky Q uses a wideband LNB which is incompatible with most models of Freesat receiver. A "Hybrid" Sky Q LNB can ...
A Viewsat Xtreme FTA receiver. A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-4/DVB-S2 standard and formerly the MPEG-2/DVB-S standard, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
