What is Ka-Band?
High Frequency:
Uplink frequencies 27-31 GHz
Downlink frequencies: 17-22 GHz
Ku Rx Band
Ka Rx Band

What’s Special about Ka-Band?
Due to the high frequencies, antenna mechanical and
electrical performance must be superior to meet RF
requirements.
Reflector surface accuracy for gain and sidelobes
Stiff pedestal needed for wind performance
Low backlash for pointing accuracy
Attention of Thermal design of Station

What’s Special about Ka-Band?
Pedestal Stiffness and
backlash.
Pedestal adequate for
Ku-Band (0.5 dB gain loss)
gives about 3 times the
