Tallysman TW3430/TW3432 GPS/GLONASS Precision Timing Antenna

The TW3430/TW3432 is a professional grade GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1574 to 1606 MHz).



The TW3430/TW3432 is especially designed for precision timing applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal rejection.

The TW3430/TW3432 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/TW3432 is housed in a permanent mount industrial-grade weather-proof dome shaped enclosure, and comes with a TNC Jack (female) connector.
