Signal converter for use in installation with a large number of participants
The LNB is equipped to provide reception of all analogue and digital TV, radio and multi-media contents broadcast via satellite. The Quattro LNB features four outputs, and has been specially designed for use in installations with several participants. The use of the Quattro LNB is particularly recommended in any case where more than four participants are connected to an installation.

Function of the LNB
The LNB (Low Noise Block Converter resp. signal converter) is the electronic component that receives the signal, and is attached to the AZ/EL mount, or feed arm, on the satellite dish. Its function is to amplify the high-frequency signals received by the antenna, and to convert these into lower frequencies. The process involves combining the input frequency range of the LNB with a Local Oscillator Frequency (LOF), and bringing it down to the so-called satellite intermediate frequency or satellite IF. The satellite intermediate frequency is identical to the output frequency range of the LNB, and can be calculated as the difference between the input frequency and the LOF. It is this transformation that makes it possible to pass on the information transmitted and received via the co-axial cable to the receiver with a minimum of loss.

Signal processing (frequency band, polarisation, satellite block)
The frequency range between 10.70 and 12.75 GHz is utilised for the reception of programmes via satellite. However, this frequency range cannot be converted to the satellite IF in a single step, therefore the frequency range is divided into an upper and a lower frequency band, known as low band and high band. In order to be able to handle a maximum number of channels within these two frequency bands, signals are transmitted in both a horizontal and a vertical polarised plane. This means that each frequency can be used for two separate channels.The combination of frequency band and polarisation plane is referred to as a satellite block. Generally speaking, four satellite blocks will be broadcast from the satellite: horizontal low band, vertical low band, horizontal high band and vertical high band. Universal LNBs cover the entire frequency range involved in satellite reception. They are able to convert all four satellite blocks, and to process both analogue and digital signals.

Multi-switches (essential in combination with the use of Quattro LNBs)
As only a single satellite block signal is provided at each output of the TechniSat UNYSAT Universal Quattro LNB (and not the entire frequency range), a multi-switch is required in order to distribute the signal to the various participants in the system. This system then takes over the switching operations between the individual satellite blocks, so that the entire frequency range required for satellite reception is available at each output of the multi-switch, and is thus available for each participant. This means that reception units such as digital receivers cannot be connected directly to the Quattro LNB.

Weatherproofing
The TechniSat UNYSAT Universal Quattro LNB is a powerful reception unit that is reliably protected from the influences of weather by a robust weatherproof housing. The housing is simply slipped onto the AZ/EL mount, and fixed in position with a single screw. No additional bracket is required for this.Attaching the co-axial cables is also child?s play. All you need to do is to remove the lower section of the weatherproof housing, this will expose the connections provided on the LNB. Installation example for 16 participants, using a TechniSwitch multiswitch This example shows how 8 to 16 receivers can be supplied with the TV and radio signals from a single satellite position. This distribution system can be simply and easily installed, using a combination of a TechniSwitch 5/8 basic unit together with a TechniSwitch 5/8 cascade. The basic requirements are an external installation (consisting of a satellite dish antenna with an AZ/EL mount as well as a Universal Quattro LNB - preferably with a weatherproof housing) as well as 2 multi-switches (basic unit and cascade), 16 satellite receivers, 16 antenna sockets and the appropriate cable lengths as required, with the appropriate number of F-connectors.
HDTV

HDTV

HDTV stands for High Definition Television, thus for outstanding picture quality. With HDTV, pictures can be displayed in much greater detail and with much finer gradations. Contrast and contours are more precise and colours truer to their originals. Furthermore, the wide screen format on HDTV broadcasts corresponds much better to human visual perception. So it creates a more vivid impression overall.
