TW2405/TW2407

The TW2405/TW2407 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.

Features

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

Benefits

  • 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 TW2407 includes a tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

IMPORTANT: Please consider using the TW2406 or TW2408 in place of the TW2405 or TW2407 respectively. The TW2406/TW2408 is 4 mm wider in diameter which permits the placement of drilled plated holes to provide a more secure means of attaching the antenna to your product. The TW2406/TW2408 is electronically identical to the TW2405/TW2407.

OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules.
