GNSS antennas
TW8889 | Dual Band Antenna
These high performance antennas have been especially chosen for their excellent performance/size compromise.
The TW8889 provides multi-constellation tracking capabilities, supporting a range of satellite systems including GPS L1/L2, GLONASS G1/G2/G3, BEIDOU B1/B2, GALILEO E1/E5b, and SBAS (WAAS/EGNOS/MSAS) signals.
Antenna usage for RTK, PPP and PPK
While this antenna offers a great mix of size and performance, they are not recommended for applications where reliable RTK, PPP or PPK is required.
They are however very good in standalone/SBAS GNSS.

We sell these antennas with a 100mm ground patch included.
Mechanical drawing
We provide only the flat radome version of the antenna.
Both the flat and conical radome have same performances. The conical radome is useful for applications where there is a risk for the accumulation of a substance on top of the antenna (such as snow).
HC977XF | Triple band Helical Calian Antenna
This multi constellation triple band (L1/L2/L5) antenna is particularly adapted for precision UAV applications, thanks to an ultra compact design, low power consumption and no ground plane requirement.
This antenna provides a triple frequency tracking on GPS, QZSS, GLONASS, GALILEO and BEIDOU and tracking of Navic in its L5 band
This antenna feature extra filtering elements for better interference rejection.
