LNCs are supplied with power by means of the coaxial cable, to achieve this the receiver supples either 14 or 18 volt power

Interim frequency:

The frequency range broadcast by the satellite cannot be transmitted via a cable. Therefore the LNC converts the sig- nal to the interim frequency range of 950 to 2150 MHz. This makes it possible for the digital receiver to receive and pro- cess the signal.

1. IF = Interim frequency
