Is Ku-Band or C-Band preferable in Africa?
Because of C-Band’s lower sensitivity to rain attenuation, C-Band systems exhibit a more constant signal strength. However, due to the fact that Ku-band antennas of the same size feature a much higher gain, Ku-band system feature a higher margin for rain attenuation. Thus, if properly designed, both Ku-Band and C-Band systems work equally well, with the advantage of lower hardware cost going to the Ku-Band system. atrexx has precise link budgets available for the entire African continent with yearly availability of the VSAT as a function of antenna size and transmitter power.
