Tallysman TW7900P Passive Triple-Band GNSS Antenna with L-Band

The TW7900P passive triple-band GNSS antenna with L-Band supports coverage for GPS/QZSS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1/B2/B2a, as well as SBAS (WAAS/EGNOS/MSAS) and L-Band correction services.



The TW7900P passive triple-band GNSS antenna with L-Band provides superior axial ratio, a linear phase response, and tight Phase Centre Variation (PCV). This antenna is ideal for re-radiating systems.

Architecturally, the TW7900P features a dual feed circular stacked patch element. The input signal is split into two orthogonal feeds used to excite the dual-pin patch antenna elements. The TW7900P provides re-radiation for signals in the bands 1164MHz to 1254MHz and 1525MHz to 1606MHz. It is housed in a magnetic mount, weather-proof enclosure.

The TW7872 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
