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.

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.
