L2 band radiation patterns 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. RHCP Realized Gain [dBic] - Elevation Cuts A 135 degree beamwidth ensures excellent...

Excellent Group Delay Variation Using GPS signal carrier phase to increase accuracy in GNSS applications has been proven reliable and has made mm-level accuracy possible. However, 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. Filtering and LNA Performance Maxtena’s M8HCT-A-SMA antenna has a flat response over the L1,...
