OVERVIEW
L1/L2b High Performance RTK GNSS Active Quad Helix Antenna
This is an active four-star full-range, high-accuracy, GNSS antenna for the GPS L1/L2, GLONASS G1/G2/G3, GALILEO E1/E5b, BDS B1I/B2I/B1C/B2b, SBAS L1, QZSS L1/L2 bands. The antenna is designed for applications requiring greater accuracy than L1, L1/L2 and L1/L5 -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.
