TW3400 Permanent Mount GPS/GLONASS Antenna The TW3400 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 rejection. The TW3400 features a highly circular dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per TW3400 Dimensions (mm) feed, a mid section SAW to filter the combined output, and a final output gain stage. This conf iguration provides excellent axial ratio that is constant across the full frequency band. The TW3400 is housed in a permanent mount industrial-grade weather-proof enclosure, and comes with a TNC Jack (female) connector. Applications High Accuracy & Mission Critical Global Positioning Precision Agriculture, Mining & Construction Military & Security Avionics Law Enforcement & Public Safety Fleet Management & Asset Tracking Features Benefits Great axial ratio: 1 dB typ.
