Tallysman TW3370/TW3372 Wideband GPS/GLONASS Antenna

The TW3370/TW3372 is a high Gain (40dB) GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It features a patch element with 40% wider bandwidth than previously available in this format. Both GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth.

The TW3370/TW3372 has a three stage Low Noise Amplifier with a mid-section SAW. A tight pre-filter is available with the TW3372 to protect against saturation by high level sub-harmonics and L-Band signals making it suitable for timing applications.

The TW3370/TW3372 has a 19mm (3/4 Inch) though hole, permanent mount white-metal base, with an industrial-grade, IP67 compliant conical radome. Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).


  • High gain LNA: 40dB
  • High rejection SAW filter
  • Low noise: 1dB
  • Temperature compensating LNAs


  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
  • temperatures

The TW3372 is a prefiltered version of the TW3370
