SSA01 Wide Bandwidth  S-Band Patch Antenna 


The EXA SSA01 is a wide bandwidth S-band antenna than can accommodate a bandwidth of up to 195 MHz for missions that need greater speed and/or bandwidth separation capabilities and great flexibility on the final frequencies selection. It will work between 2025 and 2120 MHz and 2200 and 2300 MHz without sacrificing gain, allowing your mission to not wait for the final bands and frequencies approval: By the time you get your approval papers from your telecommunications authority, you will be ready to fly, just request a frequency within SSA01’s ample range and you save at least 6 months of red tape time.
