TW2410/TW2412

The TW2410/TW2412 employ Tallysman’s unique Accutenna® technology which provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher positional and timing accuracy. The TW2410 covers the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). The TW2410 is also available in an OEM / embedded version – the TW2405.

Features

  • Low Axial Ratio
  • Tight Phase Centre Variation
  • High rejection SAW filter
  • Low noise LNA: 1dB
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Excellent choice for single frequency RTK systems
  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

The TW2412 has an additional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW2410/TW2412 are housed in compact, magnetic mount, IP67 compliant housings. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface.

They are RoHS and REACH compliant.
