circular left or circular right). Reception of 
both types of polarisation requires two 
single LNBs or a V/H-LNB (Universal 
LNB).
Receiver: see satellite receiver 
Satellite: 
A designation for the transmitting unit in 
space. Most often referred to by name 
and position, e.g. ASTRA 19° East, 
EUTELSAT 13° East 
Satellite receiver: 
The signals received and converted by 
the LNB cannot be processed by the TV. 
The satellite receiver processes them, 
and transmits audio and video signals 
(AV) to the TV through its outputs. 
SCART: 
A connector on TV sets, VCRs, satellite 
receivers and other entertainment 
equipment for transmission of audio 
(sound) and video (picture) signals (AV). 
Transponder: 
Carries out the processing of one or 
more programmes from a satellite, i.e. 
reception of data from earth station, 
amplification and radiation/transmission 
to earth. 
Universal LNB: 
A designation for a three-band LNB. For 
reception of the ranges FFS (10.70 -
11.70 GHz), BBS (11.70 - 12.50 GHz) 
and FFS High Band (12.50 - 12.75 GHz). 
The total range is divided into two bands: 
Low Band: 10.70 - 11.80 GHz; LOF 9750 MHz 
High Band: 11.70 - 12.75 GHz; LOF 10600 MHz 
Power supply: 
LNBs are powered through the coaxial 
cable to which the receiver supplies a 
voltage of 14 or 18 Volt. 
Outdoor unit: 
A designation for the equipment 
mounted outside, consisting of satellite 
dish/offset dish and one or more LNBs 
for reception of signals from one or more 
satellites, and  DiSEqC converters, if 
any. 
Viacces:
