Maxtena M9HCT-A-SM Antenna

Maxtena M9HCT-A-SM Antenna is an active multi-frequency and high-accuracy GNSS antenna. This antenna covers the L1/L2/L5 GPS, Galileo, Beidou, GLONASS bands, and L-band correction services. The M9HCT-A-SM antenna is designed for applications requiring greater accuracy than L1-only antennas can provide. This antenna is built on proprietary Maxtena Helicore® technology providing exceptional pattern control, polarization purity, and high efficiency in a compact form factor. The M9HCT-A-SM antenna features an integrated SMA connector and rugged IP67 automotive grade components. This antenna is ideal for applications requiring minimal integration effort or for retrofitting existing products.

The M9HCT-A-SM antenna is equipped with an O-ring and operates from -40°C to 105°C. Typical applications include autonomous Unmanned Aerial Vehicles (UAVs), GNSS positioning, GNSS timing, sea and land container tracking, fleet management, law enforcement, and public safety.
