Echo 50Embedded Active L1, L2, L5 & L6 GNSS Antenna

The Echo 50 is an active high-precision GNSS antenna designed for exceptional multi-constellation performance across all GPS, GLONASS, BeiDou, Galileo, NavIC, and QZSS bands. Integrated with a high-quality low noise amplifier, it delivers enhanced sensitivity and ensures reliable reception in challenging environments. With wideband support and low axial ratio, it enables sub-meter positional accuracy, and when paired with RTK corrections, centimetre-level precision is achievable.

Exceptional axial ratio, high gain, and pattern stability are achieved through the use of two orthogonal feeds in each patch, merged via a hybrid coupler. This ensures that the antenna delivers solid GNSS performance in challenging reception environments.

Supplied with a 0.1 m cable and SMAM, I-PEX MHF1, or MHF4 connector as standard, customised options are also available for high-volume orders.

Key Features

• Covers all major GNSS bands worldwide, improving accuracy, reducing multipath errors and increasing satellite availability.
• Active design with integrated LNA giving 23 ± 2 dB gain and ≤ 1.5 dB noise figure.
• Low VSWR across all bands (1.42 – 1.97), minimising signal loss.
• Axial ratio as low as 0.02 dB at zenith for excellent circular polarisation.
• Peak RHCP gain up to 27.19 dBiC for strong signal lock.
• Compact embedded form for easy integration.

Additional Considerations

• Results shown are based on anechoic chamber test in free space with 0.1M Cable and an SMA Male connector
• Magnetic mount and adhesive mount outdoor options with plastic enclosure available through customisation
