M7HCT-A-SMA L1: GPS, GLONASS, GALILEO, BEIDOU L2: GPS L2C, GALILEO E5B, GLONASS L3OC Part : 100-00069-01 Description The M7HCT-A-SMA is an active multi-frequency, high-accuracy, GNSS antenna for the L1/L2 GPS, Galileo, Beidou and GLONASS bands. The antenna is designed for appli- cations 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 M7HCT-A-SMA is ideal for applications requiring minimal integration effort or for retrofitting existing prod - ucts. The antenna is equipped with an O-ring.

Low axial ratio not only at the zenith, but also in other elevation angles ensures multipath error is mitigated. 2. Full hemispherical coverage is achieved by an exceptionally large 3 dB beamwidth, ensuring full view of sky and satellites in lower elevation angles. 3. Highly symmetric radiation pattern guarantees there will be no direction of weak reception or blind spots.
