A Tallysman Accutenna® TW2920 Wideband GPS/GLONASS/BeiDou/Galileo + L-Band Antenna The TW2920 is an Accutenna technology antenna that covers GPS L1, GLONASS G1, BeiDou B1, Galileo E1, SBAS (WAAS, EGNOS, GAGAN, & MSAS) and the downlink L-Band (1525 – 1559MHz). The TW2920 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV). This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters. Dimensions (mm) The TW2920 features a dual-feed wideband patch element, plus a low-loss pre-filter followed by a three stage Low Noise Amplifier (LNA) including an additional mid-section SAW. This configuration provides excellent axial ratio across the full frequency band and strong protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi. The TW2920 has a compact, robust, magnetic mount housing with a metal base and a UV resistant, tough wide temperature range plastic radome, and is available with a variety of connectors. The housing includes a screw down option, and is available with an adhesive attachment, without a magnet, Dimensions (mm) The TW2920 is also available with an “armoured” cable. option, with the cable encased in tough corrugated conduit having a temperature range of -40 to +120C, excellent chemical resistance, stable bending, high cold impact strength, and UL94HB flammability standard compliant.
