SSA03 Compact High Gain S-Band Patch Antenna 


The EXA SSA03 is a very compact, high gain S-band antenna that can accommodate a bandwidth of up to 30 MHz for missions that need greater speed and/or bandwidth separation capabilities and great flexibility on the final frequencies selection.


Integrated user selectable choice between LCHP and RHCP and center frequency choice between 2220 and 2260 MHz allows your mission to not wait for the final bands and frequencies approval and greater flexibility: By the time you get your approval papers from your telecommunications authority, you will be ready to fly, just request a frequency within SSA03’s ample center frequency range and you save at least 6 months of red tape time.
