Tallysman TW3740 Single-Band GNSS Antenna
The TW3740 single-band GNSS antenna employs Tallysman's unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS/EGNOS/MSAS).
Description
Overview
Ideal for professional precision timing applications, TW3740 single-band GNSS antenna provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.
The TW3740 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 TW3740 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours. Two options for pole mounting are available an L-Bracket or a Pipe Mount.
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW3742 provides these additional benefits with an LNA pre-filter.
