## **L2 Band Radiation Patterns** 

Maxtena M9706CWT-UFL 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. 

**RHCP Realized Gain [dBic] - Elevation Cuts** 

**RHCP Realized Gain [dBic] - Azimuth Cuts** 

A 117 degree beamwidth ensures excellent hemispherical coverage.

## **Excellent Group Delay Variation** 

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 M9706CWT-UFL has a flat response over its specified GNSS bands and has minimal group delay variation over frequency. 

## **Filtering and LNA Performance** 

Maxtena’s M9706CWT-UFL antenna has a flat response over both L1 and L2 GNSS bands, with less than 1 dB variation over each band. The superior out-of-band rejection ensures minimal interference. 

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. 

< 2 ns group delay variation over L2-band.
