The TW2406 is electronically identical to the TW2405 with the same performance characteristics. The TW2406 has a larger PCB than the TW2405 (56mm versus 50mm) with drilled holes to permit more secure mounting The TW2406/TW2408 employ Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.


  • Accutenna™ Technology
  • Tight Phase Centre Variation
  • Highest accuracy GPS + GLONASS OEM antenna in its size range
  • High rejection SAW filter
  • Temperature compensating LNAs


  • Superior multipath signal rejection
  • Ideal for handheld devices
  • Improved carrier phase linearity for RTK systems
  • Excellent signal-to-noise ratio
  • Consistent response in all operating temperatures
The TW2408 includes a tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals. OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules. For further details, please download the Datasheet.
