SSA02 34dB Wide Bandwidth  Amplified S-Band Patch Antenna 


The EXA SSA02 is the power-amplified version of the SSA01 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 SSA02’s ample range and you save at least 6 months of red tape time.

SSA02 gives your mission’s link budget a powerful boost thanks to its onboard amplifier tied directly to the antenna, working alongside a RF switch chip that allows safe transceiver capability to your radio; the total ERP delivered by the SSA02 is a powerful 34 dB allowing the use of very low power radios, thus saving power without sacrificing link budget. 

This also means that 2 radios can share the same antenna!
