Overview

The TW3430 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 timing applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal rejection.

The TW3430 features a highly circular 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 TW3430 is housed in a permanent mount industrial-grade weather-proof dome shaped enclosure, and comes with a TNC Jack (female) connector.
