İngilizce - İngilizce
= Low Noise Block = device that down converts the High frequency signals from a satellite to a range which can be "seen" by the satellites tuner using a Local Oscilator  - Typically an LNB will have two of these a "Universal" LNB will have a Local Oscillator set at 9 75 Ghz  and another at 10 6 Ghz this higher one is activated by the receiver sending a 22Khz Tone
Low Noise Block Downconverter
Low Noise Block Amplifier/Converter: hardware device for converting and amplifying a band of satelllite signals from a high frequency (usually GHz) into lower IF-frequency(usually MHz) The LNB is mounted in the focal spot of a satellite dish
A special amplifier that boosts the satellite signal while contributing a negligible amount of noise It also converts a signal to a more suitable band of frequencies for reception
Low Noise Block converter The device in an antenna which points at the satellite The LNB amplifies the received signal and converts it to an intermediate frequency
Low Noise Block - Part of the antenna dish that amplifies the received signal from the antenna and converts it from a microwave signal to a lower frequency signal The lower frequency signal, can then be carried on coaxial cable to the DirecPC adapter
Part of a LNBF
The Low Noise Blockdown amplifier performs the same functions as the LNBF
Satellite receiving equipment that converts all signals from the LNA to the lower IF frequencies
Low Noise Block Downconverter A device that processes weak satellite signals directed by an antenna reflector into a feedhorn, whilst introducing as little electrical noise as possible in the process An LNB consists of a microwave detector followed by a high gain, low noise microwave amplifier and a frequency converter, which downconverts a block of frequencies (group of satellite signals) to a lower intermediate frequency range (typically 950 to 2150 MHz) The feedhorn is often integrated with LNB in a single mechanical unit
