A 135 degree beamwidth ensures excellent hemispherical coverage. Symmetric coverage even in low elevation enhances accuracy. Maxtena’s M8HCT-A-SMA has unique features that make it the best option for high-accuracy GNSS applications. 1. 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.

Flat conducted gain response. < 2 ns group delay variation over L2-band. < 2 ns group delay variation over L1-band. Using GPS signal carrier phase to increase accuracy in GNSS applications has been proven reliable and has made mm-level accuracy possible. How- ever, in resolving carrier phase ambiguity, it is necessary to make sure carrier phase is received and measured accurately and that the effect of antenna and receiver on carrier phase is minimized. Maxtena’s M8HCT-A-SMA has a flat response over all GNSS bands that it covers and has minimal group delay variation over frequency. Maxtena’s M8HCT-A-SMA antenna has a flat response over the L1, L2 and L5 GNSS bands, with less than 1 dB variation over each band. The superior out-of-band rejection ensures minimal interference. Excellent Group Delay Variation Filtering and LNA Performance < 2 ns group delay variation over L5-band. Maxtena Inc.
