What is Ka?

• 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.

• Ka band satellites typically transmit with much more power 

than C band satellites.

• The higher frequencies of Ka band are significantly more 

vulnerable to signal quality problems caused by rainfall, 
known as rainfade.
