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
