Siretta Echo 50 Active Multi-Constellation GNSS Antennas
Siretta Echo 50 Active Multi-Constellation GNSS Antennas offer high precision for exceptional multi-constellation performance across all GPS, GLONASS, BeiDou, Galileo, NavIC, and QZSS bands. These high-precision, ceramic patch antennas feature a compact embedded form for easy integration and come with a 0.1m cable with a SMAM, I-PEX MHF1, or MHF4 connector as standard. The integrated low-noise amplifier (LNA) provides enhanced sensitivity and reliable reception in challenging environments. With low axial ratio and wideband support, the Echo 50 series enables sub-meter positional accuracy. When paired with real-time kinematic (RTK) corrections, centimeter-level precision can be achieved. Siretta Echo 50 Active Multi-Constellation GNSS Antennas utilize two orthogonal feeds in each patch, merged via a hybrid coupler, delivering high gain, exceptional axial ratio, and pattern stability for a wide range of applications.
