TW3142 Single Band GNSS Antenna

Tallysman TW3142 Single Band GNSS Antenna

The TW3142 single band GNSS antenna from Tallysman supports coverage for GPS/QZSS L1, as well as SBAS (WAAS/EGNOS/MSAS).



The TW3142 single band GNSS antenna from Tallysman is a high-gain GPS antenna specifically designed for applications in environments where high levels of near- out-of-band interfering signals can be expected. This antenna features a 40dB LNA gain to handle long cable runs.

The TW3142 covers the GPS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band and employs Tallysman’s unique Accutenna technology to provide excellent cross polarization rejection and greatly enhanced multipath rejection.

The TW3142 features a three (3) stage dual filtered LNA plus an additional SAW pre-filter to provide exceptional rejection of close out-of-band signals and additional protection against saturation by high level sub-harmonic and L-Band signals.

The TW3142 housing has a permanent mount, IP67 compliant metal base, and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.

Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
