Overview

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 – 1559 MHz). 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.

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.

The TW2920 is also available with an “armoured” cable. option, with the cable encased in tough corrugated conduit having a temperature range of -40 °C to +120 °C, excellent chemical resistance, stable bending, high cold impact strength, and UL94HB flammability standard compliant.
