TW2405 Embedded GPS/GLONASS Antenna The TW2405 by Tallysman Wireless is a professional grade embedded GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It is especially designed for precision industrial, agricultural and military OEM applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal ejection. The TW2405 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, TW2405 Dimensions (mm) 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 TW2405 comes in a compact circular form fac tor with a built-in 50 mm diameter ground plane, and a 15 cm RG174 cable. Applications High Accuracy & Mission Critical GPS Precision Agriculture, Mining & Construction Military & Security Avionics Law Enforcement & Public Safety Fleet Management & Asset Tracking Features Benefits Great axial ratio: <3 dB over full bandwidth Excellent multipath rejection Low noise LNA: 1 dB Increased system accuracy High rejection SAW filter Excellent signal reception High gain: 28 dB typ. Great out of band signal rejection Low current: 10 mA typ.
