The TW2920 provides superior multipath 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 subharmonic 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 +120C, excellent chemical resistance, stable bending, high cold impact strength, and UL94HB flammability standard compliant. ## Applications - High-accuracy & mission-critical global positioning - Precision agriculture, mining, and construction - Law enforcement and public safety ## Features - Low loss Great axial ratio: 1 typ., 3 dB max - Low noise LNA: ≤ 2.5 dB typ. - High-rejection SAW filter - Wide voltage input range: 2.5 to 16 VDC - IP67 weather proof housing ## Benefits - Excellent multipath rejection - Increased system accuracy - Excellent signal-to-noise ratio - Great out-of-band signal rejection - Ideal for harsh environments - RoHS and REACH compliant About Calian: With global headquarters and manufacturing in Ottawa, Canada, Calian is a leading manufacturer of highprecision antennas and components for Global Navigation Satellite System (GNSS) applications. Calian’s mission is to support the needs of a new generation of positioning systems by delivering unprecedented antenna precision at competitive prices.
