Echo 50 Embedded Active GNSS Antennas

The Siretta Echo 50 is an embedded active GNSS antenna designed for applications that require stable, repeatable positioning performance across multiple satellite constellations. It uses a stacked ceramic patch architecture with right-hand circular polarization (RHCP) to maintain consistent gain and axial ratio across the L-band GNSS spectrum, even in constrained or electrically noisy installations.

Covering 1.176 GHz to 1.602 GHz, the Echo 50 supports GPS, GLONASS, Galileo, BeiDou, QZSS, and related GNSS services through a single active antenna. An integrated low-noise amplifier provides high gain while maintaining a low-noise figure, making the antenna suitable for embedded receivers, timing modules, and precision navigation platforms where link margin and multipath control matter.

With a compact 60 mm x 60 mm x 18.8 mm form factor and a 0.1 m RG 174 cable terminated in an SMA male connector, the Echo 50 is intended for straightforward mechanical and RF integration. The design is ground plane independent and rated for industrial temperature operation, supporting reliable use in fixed and mobile equipment.
