DATASHEET WIRELESS INNOVATIONS COMPANY M8HCT-A-SMA FEATURING PROPRIETARY HELICORE TECHNOLOGY The M8HCT-A-SMA is the worlds most advanced patented GNSS antenna. Designed for high precision & autonomous multi-frequency applications. The rugged active quadrifilar helix antenna is manufactured using automotive grade electronics for GIS, RTK and other GNSS applications. The revolutionary design offers concurrent reception on L1: GPS, GLONASS, Galileo, Beidou L2: GPS L2C, Galileo E5B, GLONASS L30C and L5: the most advanced GNSS signal yet.M8HCT-A-SMA L1: GPS, GLONASS, GALILEO, BEIDOU L2: GPS L2C, GALILEO E5B, GLONASS L3OC L5: GPS Part : 100-00124-01 Description The M8HCT-A-SMA is an active multi-frequency, high-accuracy, GNSS antenna for the L1/L2/L5 GPS, Galileo, Beidou and GLONASS bands. The antenna is designed for ap- plications requiring greater accuracy than L1-only antennas can provide. The antenna is built on proprietary Maxtena Helicore 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. The M8HCT-A-SMA is ideal for applications requiring minimal integration effort or for retrofitting existing prod - ucts. The antenna is equipped with an O-ring.
