Echo 52Embedded Active Multi-Constellation GNSS L1/L2/L5 Ceramic Patch Antenna

The Echo 52 is an embedded multi-band GNSS antenna that delivers high accuracy positioning across the L1 (1575 MHz), L2 (1227 MHz) and L5 (1176 MHz) bands. It supports all major constellations including GPS, Galileo, BeiDou, QZSS and NavIC, enabling broad global compatibility for navigation, location and timing applications.

Its stacked ceramic patch structure and two-stage LNA provide strong RHCP gain with excellent axial purity, yielding robust performance even in low-signal or multipath environments. The antenna’s directional pattern ensures maximum efficiency in the upper hemisphere, making it ideal for embedded GNSS modules and compact systems requiring precision tracking or RTK capability.

Available with MHF1/UMCC/U.FL or SMA connectors and 1.13 mm miniature coax cable as standard. Alternative lengths and connector types can be specified for high-volume orders.
