KU Band LNB
- Ku Band Frequencies are from 12 to 18 GHz.
- Beyond that KU-band requires a much smaller antenna and is less susceptible to variations in weather and interference cause by the leaves of trees and other terresterial interferences.
- Ku-band frequencies are dedicated for satellite communication only.
- Ku-band frequencies are dedicated for satellite communication only. This solves the problem of interfering with terrestrial microwave backhaul links.
- Ku-Band is characterized by its high powered signals compared to C-band.
- Ku-Band is characterized by its high powered signals compared to C-band. Thus, smaller dishes can be used to achieve the same distance as C-band and the KU band radio transmitter also requires less power.
- Normally, 0.9, 1.2 or 1.8 meter dish is used for Ku-Band applications.
- Normally, 0.9, 1.2 or 1.8 meter dish is used for Ku-Band applications. This can save great CAPEX and makes Ku-band suitable for small networks.
- However, Ku-band is more sensitive to rain fade and the attenuation due to rainfall can be up to 10 dB.
- Ku-band is preferred for cases where there is a limited area for installation, because a smaller dish size is needed and it is easy to install.
- From a commercial point of view, Ku-band is better for satellite applications that need smaller bandwidth, as the equipment is cheaper than C-band.
