TW2400 Magnet Mount GPS/GLONASS Antenna The TW2400 by Tallysman Wireless is a professional grade GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1574 to 1606 MHz). It is especially designed for precision industrial, agricultural and military applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal rej ection. Dimensions (mm) p/n 32-2400-0 The TW2400 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band. The TW2400 is housed in a compact, industrial- grade weather-proof, magnet mount enclosure, and comes with a bulkhead SMA female connector or with 5 metres of cable and a wide Dimensions (mm) p/n 32-2400-7 ran ge of connector. Applications High Accuracy & Mission Critical Positioning Precision Agriculture, Mining & Construction Military & Security Avionics Law Enforcement & Public Safety Fleet Management & Asset Tracking Features Benefits Great axial ratio: 1 typ., 3 dB max Excellent multipath rejection Low noise LNA: 1 dB Increased system accuracy High rejection SAW filter Excellent signal to noise ratio High gain: 28 dB typ.
