What is the difference between Ka band satellites and Ku band satellites?

There are more than 22 FSS Ku band satellites orbiting over North America, each carrying 12 to 48 transponders, 20 to 120 watts per transponder, and requiring a 0.8-m to 1.5-m antenna for clear reception.

The Ku band frequency range is 11.7 – 12.2 GHz (or 11700 to 12220 MHz) Notice how these frequencies are higher than the C band frequency range. Because of the higher frequencies, Ku band waves have shorter wavelengths . Shorter wavelengths mean that you need a smaller dish to receive these frequencies.

1. What are the main differences between Ka band and Ku band? One major difference is the frequency of each band, which affects the quality of the connection provided. Ku-band uses frequencies in the 12 to 18 GHz range, while Ka-band uses frequencies in the 26.5 to 40 GHz range .24 Eyl 2019

Ku-band (12–18 GHz ) Used for satellite communications. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra.
