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 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.
Switching criteria

Both 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.
Weatherproofing
The 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.
