Tallysman TW3440/TW3442

The TW3440/TW3442 employ Tallysmans unique Accutenna® technology covering the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides circular response over its entire bandwidth thereby producing multipath signal rejection resulting in higher accuracy of position and timing.


  • Accutenna® Technology
  • High Gain 40 dB
  • High rejection SAW filter
  • Low noise LNA: 1dB
  • Temperature compensating LNAs


  • Superior multipath signal rejection
  • Ideal for Timing applications
  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
  • temperatures

The TW3442 has an additional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW3440/TW3442 are housed in a through-hole mount, weather-proof enclosure for permanent installations. They are available with either a flat or conical radome in either grey or white. The TW3440/TW3442 is also available with either a TNC or N-Type connector on the base of the antenna or with a flying lead and a variety of connectors.

LNA Pre-filter 

If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, select Pre-Filter for this product. If you have questions, contact us. 

To minimize performance impact from signal jamming threats, the pre-filtered version of this antenna is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
