Frequently Asked Questions

What is an LNB?

An LNB (Low Noise Block, also called LNC - Low Noise Converter) is used for broadcast satellite reception. The LNB is typically mounted on the satellite dish and serves to collect and amplify the satellite signal received from the dish, then down-converts the signal to a lower, more manageable IF frequency that can be carried over standard coaxial cabling to the receiver. LNBs are categorized into C-Band, Ku-Band, and Ka-Band according to their operating frequency ranges.

What is KU BAND?

This refers to the specific portion of the radio frequency spectrum it's designed to receive.

KU Band frequencies range from approximately 10.7 GHz to 12.75 GHz
This band is widely used for direct-to-home (DTH) satellite television across Europe, the Middle East, Africa, and many parts of Asia
Distinct from C Band (older, larger dishes) and KA Band (used for high-speed internet)

What is Universal?

A "Universal" LNB is designed to cover the entire KU Band range (10.7 - 12.75 GHz) and is compatible with virtually all modern digital satellite receivers.

Universal LNB Operation

Two Internal Local Oscillators: 9.75 GHz for Low Band (10.7 - 11.7 GHz) and 10.6 GHz for High Band (11.7 - 12.75 GHz)
Band Switching: Satellite receiver sends a 22 kHz tone - OFF for Low Band, ON for High Band
Advanced Control: Uses DiSEqC (Digital Satellite Equipment Control) commands for additional functions, but the 22 kHz switching mechanism is the core of the "Universal" LNB definition.
