Transponder:

Located on the satellite, processes one or several program- mes there, ie. it receives the data from the transmitting sta- tion on the ground, amplifies the signal and broadcasts it back to earth.

Universal LNB:

Designed to receive the ranges FFS (10,70 - 11,70 GHz), BBS (11,70 - 12,50 GHz) and FFS High Band (12,50 - 12,75 GHz). The entire 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

Supply current:

LNBs are supplied with electrical current via the co-axial cable. To do this, the receiver provides a current of 14 or 18 Volt

Intermediate frequency:

The frequency range transmitted by the satellite cannot be transmitted via cable, and is therefore converted by the LNB to the intermediate frequency range of 950 to 2150 MHz. This makes transmission possible, and allows the digital receiver to process the signal.
