Tallysman TW8829 Antenna
The TW8829 from Tallysman is a dual band antenna with GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1 coverage and is especially designed for precision dual frequency positioning for applications where light weight is important, such as for unmanned aerial vehicles.
The TW8829 features a precision tuned, circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.
The TW8829 has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.
Features
- Accutenna® Technology
- Light weight (37g)
- Low noise LNA
- Temperature compensating LNAs
Benefits
- Superior multipath signal rejection
- Ideal for RTK applications
- Excellent signal-to-noise ratio
- Consistent response in all operating temperatures
Tallysman recommends using this antenna with a 12cm circular ground plane to improve the gain of the antenna, particularly at the L2 frequency.
The TW1829 is REACH and RoHS compliant.
