TW3100 GPS Precision Positioning Antenna
The TW3100 by Tallysman Wireless is a professional grade, permanent mount GPS L1 antenna, specially designed for professional precision tracking and timing applications.
The TW3100 features a custom high performance, dual-feed, wide band patch element. Its LNA configuration provides a LNA for each feed, a mid section high rejection SAW for the combined signal, followed by a final stage of LNA. It provides ±10MHz bandwidth centred on 1575.42 MHz and covers all GPS L1, Galileo E1 and SBAS (WAAS/EGNOS/MSAS) signals. It features great axial ratio over the entire frequency range (<3dB), excellent circular polarized signal reception, great multipath rejection and out-of-band signal rejection.
The TW3100 is housed in a permanent mount industrial-grade weather-proof enclosure, and comes with a TNC Jack (female) connector.
