C-band satellite<p>C-band is the original frequency allocation for communications satellites. C-Band uses 3.7-4.2GHz for downlink and 5.925-6.425Ghz for uplink. The lower frequencies that C Band uses perform better under adverse weather conditions than the Ku band or Ka-band frequencies.</p> <p>See also: <a href="https://en.wikipedia.org/wiki/C_band_(IEEE)">C-band</a></p>
