A 117 degree beamwidth ensures excellent hemispherical coverage. Symmetric coverage even in low elevation enhances accuracy. Maxtena M9708CWT uses patented optimized microstrip technology which results in minimal dependence on frequency and features a wide beamwidth, low axial ratio and radiation pattern symmetry across all desired frequencies in L1, L2, and L5 bands.

A 117 degree beamwidth ensures excellent hemispherical coverage. Symmetric coverage even in low elevation enhances accuracy. Maxtena M9708CWT 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 at lower elevation angles. 3. Highly symmetric radiation pattern guarantees there will be no direction of weak reception or blind spots. L2 band radiation patterns Maxtena Inc.

< 2 ns group delay variation over L2-band. Outstanding out-of-band rejection and less than 1dB fluctuation of in-band frequency response over L2-band. Outstanding out-of-band rejection and less than 1dB fluctuation of in-band frequency response over L1-band. Using GPS 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 the effect of antenna and receiver on carrier phase is minimized. Maxtena’s M9708CWT has a flat response over its specified GNSS bands and has minimal group delay variation over frequency. Maxtena’s M9708CWT antenna has a flat response over L1 and L2 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 L1-band. Maxtena Inc.
