L1 HIGH PERFORMANCE GNSS ACTIVE QUAD HELIX ANTENNA FOR DRONES OR ROBOTS

High Performance GNSS L1 Active Quad Helix Antenna for Drones or Robots description:

This is an active high-accuracy, GNSS antenna for the GPS/SBAS/QZSS L1, Glonass G1, Beidou B1I/B1c, Galileo E1 bands. The antenna is designed for applications requiring greater accuracy than L1-only antennas can provide. The antenna is built on helical structure technology providing exceptional pattern control, polarization purity and high-efficiency in a compact form factor. It 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 antenna is equipped with an O-ring.
