Signal converter for reception by two parties
This signal converter comes equipped with two independent connections, and is designed for the reception of all analogue and digital TV, radio and multi-media signals transmitted via satellite, supplying these to two participants/receivers. As the entire frequency range involved in satellite reception is available at each of the two outputs, you can attach either two reception units (e.g. receivers or TV PC card) or a twin receiver directly to the output sockets. This Twin LNB is designed for reception by no more than two participants. There is no provision for an expansion of the system via a multi-switch. In order to provide signals to more than two participants, we recommend the use of a Quatro LNB resp. of a Quatro Switch LNB. Function of the LNBThe 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. Switching criteriaBoth the conversion of the two frequency bands and the conversion of the polarisation planes are effected separately. Switching between polarisation planes takes place by means of a variation in the voltage of the current supplied to the LNB (14 Volts for the vertical resp. 18 Volts for the horizontal plane). On the other hand, the upper frequency band is controlled via a 22 KHz signal that is superimposed on the LNB power supply current. WeatherproofingThe TechniSat UNYSAT Universal Twin 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 reception by two participants In this example, the objective is to supply TV and radio signals from a single satellite position to two receivers. The basic requirements for this are an external installation (consisting of a satellite dish antenna with an AZ/EL mount and a Universal Twin LNB - preferably one with a weatherproof housing) as well as two satellite receivers, two antenna sockets, and appropriate lengths of cable with the corresponding F-connectors.




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.
