Tallysman GPS L1 | GLONASS G1 | SBAS Antenna


The TW3400 | TW3402 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 multi-path signal rejection resulting in higher accuracy of position and timing.

The benefits of the TW3400 / TW3402 include:
–  Superior multipath signal rejection
–  Ideal for use in single-frequency RTK systems
–  Great out-of-band signal rejection
–  Excellent signal-to-noise ratio
–  Consistent response in all operating temperatures

The TW3402 has an additional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW3400 | TW3402 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. They are 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.

L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. They are IP67, RoHS, and REACH compliant.
