TW3101 Single Band GNSS Antenna (Low Magnetism)

The TW3101 by Tallysman Wireless is a precision grade, permanent mount GPS L1 antenna with no magnetic properties, specially designed to be used in close proximity with compass based instruments.  

The TW3101 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 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 TW3101 is housed in a permanent mount industrial-grade weather-proof enclosure and two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
