What is the LNB frequency for KU band?

Posted on by Bravo Satcom

KU-band refers to a portion of the electromagnetic spectrum used for satellite communication. In satellite television reception, a Low Noise Block Downconverter (LNB) is a device mounted on the satellite dish. The LNB receives the signals reflected off the dish and downconverts them to a lower frequency range for easier transmission through the coaxial cable to the satellite receiver.

The Local Oscillator Frequency (LOF) of the LNB is a key parameter, and it’s set during the installation to match the frequency of the satellite signals. In the case of KU-band, the LNB frequency typically falls within the range of 10.7 to 12.75 GHz. Here’s a bit more detail:

  • LOF Standard Frequencies: Common LNB frequencies for KU-band include 10.75 GHz, 11.0 GHz, 11.3 GHz, and 12.2 GHz. These are the standard frequencies that LNBs use to downconvert the satellite signals.

  • Satellite Downlink Frequencies: KU-band satellite signals are transmitted from the satellite to the dish at frequencies in the range of approximately 12.0 to 18.0 GHz.

  • Calculation Example: If the LNB has a LOF of 10.75 GHz and it receives a signal from the satellite at 12.0 GHz, the downconverted signal sent to the receiver through the coaxial cable will be at 12.0 GHz – 10.75 GHz = 1.25 GHz.
