The TW3742 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS/EGNOS/MSAS).
Ideal for professional precision timing applications, TW3742 provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.
The TW3742 features a customizable dual-feed, wide-band patch element, and a 40 dB gain Low Noise Amplifier (LNA) with a high rejection out-of-band SAW filter, providing an excellent axial ratio that is constant across the full frequency, superb phase linear response and tight phase centre variation.
The TW3742 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
To minimize performance impact from signal jamming threats, the TW3142 is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
The TW3742 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours.
