C-Band

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 used by C-Band perform better under adverse weather conditions than the Ku-band or Ka-band frequencies.

C-Band Variants

Slight variations of C-Band frequencies are approved for use in various parts of the world.
