Signal converter for single party reception
The UNYSAT Universal V/H LNB is a Single LNB signal converter designed for use in single party reception of analogue and digital TV, radio and multi-media contents broadcast via satellite. It has a single signal output, and can be connected directly to the receiver. This type of LNB does not provide for direct connection to an additional participant (receiver or comparable reception unit). General purpose 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 V/H 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 cable 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 a single party In this example, the TV and radio signals from a single satellite position are to be supplied to a single receiver. The basic requirements for this include an external installation (consisting of a satellite dish antenna with an AZ/EL mount and a Universal V/H LNB - preferably one with a weatherproof housing) as well as a satellite receiver, an antenna socket and the appropriate lengths of cable as well as the necessary F-connectors.
