GCA01 Compact GNSS Active Patch Antenna 

€1,700

The EXA GCA01 is a one-stage, compact GNSS active patch antenna solution that works with your GNSS card and link it to GPS, GALILEO, BEIDOU and  GLONASS constellations, It is the ideal antenna for space-grade GNSS devices to achieve good sensitivity across all bands in a small form factor.

The active patch antenna, by means of a double resonance design, has a wide-band operation over GPS/GLONASS/GALILEO/BeiDou systems from 1561MHz to 1606MHz. It includes a one-stage LNA and front-end SAW filter to reduce out of band noise,  this antenna offers better protection from LEO radiation and greatly reduces the probability of damaging your GNSS receiver due to nearby transmissions.
