What Is the Difference Between a C Band & K Band Satellite Dish?


C Band and K Band frequencies mandate different speeds and broadcast range for satellite television, among other signals. Understanding the difference between the two can increase your knowledge of emerging broadcast technologies.

C Band Frequency

  • C Band frequencies are a set of radio frequencies ranging from 4 to 8 gigahertz. Early satellite television was broadcast in C Band, but with the advent of high definition, a large number of providers have switched to the more powerful K frequency.

K Band Frequency

  • K Band frequencies are a set of radio frequencies ranging from 18 to 27 gigahertz, substantially larger than a C Band frequency.

Ku Band

  • The Ku Band is slightly less powerful than the K Band, with a signal that ranges from 12 to 18 gigahertz. Many satellite television channels and providers broadcast in Ku.

K Band Advantages

  • The K Band frequency is much stronger frequency than the C Band, which makes it faster and more powerful. Thanks to its more powerful signal and broadcast range, the K Band is more fit to carry HD television.

C Band Advantages

  • Though not as powerful as the K Band, items operating on a C Band frequency can occasionally be less expensive. Since some providers have yet to switch to HD, many packages offered on C Band have a larger number of channels than packages in the more expensive K Band.
