M9706CWT

L1: GPS, GLONASS, GALILEO, BEIDOU
L2: GPS L2C, GALILEO E5B, GLONASS L3OC
Part #: 100-00090-01

Description
The M9706CWT is an active multi-frequency, high accuracy, GNSS antenna for the L1/L2 GPS, Galileo, Beidou and GLONASS bands. The antenna is designed for applications
requiring greater accuracy than L1 only antennas can provide. The antenna’s excellent
radiation pattern, exceptional out-of-band rejection, minimal group delay variation, andlow noise figure ensures optimal performance of GNSS systems. It features a 5 m cablewith an integrated SMA, SMB, or MCX connector (customer choice). The M9706CWT is
ideal for applications requiring minimal integration effort or for retrofitting existing products and is rated IP67. The antenna is manufactured using automotive grade housing.

L2 band radiation patterns
Maxtena M9706CWT 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.

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, inresolving carrier phase ambiguity, it is necessary to make sure carrier phase is received and measured accurately and the effect of antenna and receiveron carrier phase is minimized. Maxtena’s M9706CWT has a flat response over its specified GNSS bands and has minimal group delay variation overfrequency.
Filtering and LNA Performance
Maxtena’s M9706CWT antenna has a flat response over both L1 and L2 GNSS bands, with less than 1 dB variation over each band. The superior out-ofband 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
