  • Page 5 What is Ka? Confidential & Proprietary • What is Ka? • The Ka band uplink uses frequencies between 27.5Ghz and 31Ghz and the downlink uses frequencies between 18.3 and 18.8Ghz and between 19.7 and 20.2Ghz. • Ka band dishes are much smaller than C band dishes. Ka band dishes vary from 2' to 5' in diameter.
