TW3402 Single Band GNSS Antenna (Pre-filtered)

The TW3402 employs Calian's patented Accutenna® technology and covers the GPS-L1, GLONASS-G1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It is especially designed for precision industrial, agricultural, safety and security applications. The TW3402 provides truly circular response over the antennas’ entire bandwidth thereby producing superior multipath signal rejection.

The TW3402 features a highly circular dual-feed wideband patch element, with a two-stage low-noise amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides an excellent axial ratio that is constant across the full frequency band. A pre-filter on the TW3402 protects against saturation by high-level sub-harmonic and LBand signals.

The TW3402 is housed in a permanent-mount industrialgrade weatherproof enclosure. Optional components include a 10 cm ground plane (P/N 23-0067-0), an Lbracket mount (P/N 23-0040-0) or a pipe mount (P/N 23-0065-0).
