LNB
Active equipment that receives the signal (microwave) reflected by the satellite dish and converts it into radio frequency to be transmitted by the distribution system. The frequency to which the satellite signal is shifted is known as intermediate frequency (IF).
The LNB includes an amplifier with a very low noise figure (hence the name Low Noise Block), a bandpass filter that limits the noise entering the next equipment, a combiner, and a local oscillator to switch bands (18 V + 22 kHz = HH; 18 V = HL; 13 V + 22 kHz = VH; 13 V = VL); finally, there is a block for IF amplification prior to transmission.

A whole satellite distributed over a single coaxial cable
dLNB converter providing the users with the whole contents of the Astra 19º satellite. Operates in dynamic mode, in which each SAT packet that is generated is assigned to a network user by means of a User Band. With a compatible receiver, each user is able to change the packet contents at will. This method provides up to 16 UB, divided as follows: 8 UB for dCSS (SCR II), and 8 UB for dCSS/SCR I.
It is also equipped with two alignment frequencies for dish pointing: 1242 MHz (SR: 27500) and 1760 MHz (SR: 29900). -
