TW3710/TW3712 Fixed Mount Antenna
The Tallysman TW3710 /TW3712 Multi-Constellation Fixed Mount Antenna is a professional grade GNSS antenna covering the Beidou, Galileo, GPS, and GLONASS systems with an SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1557 to 1606 MHz). The TW3712 is the Pre-filtered model.
Â
Designed for high-accuracy applications, including precision industrial, agricultural and military applications, it offers excellent circular polarized signal reception, multipath rejection and out-of-band signal rejection.
Â
The TW3710/TW3712 features a 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 excellent axial ratio that is constant across the full frequency band.
Â
Minimize Signal Jamming with Tallyman’s Anti-Jamming Add On
To minimize performance impact from signal jamming threats, the TW3100 is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
Â
LNA Pre-Filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as Wi-Fi, the pre-filtered model, TW3712, provides these additional benefits with an LNA pre-filter.
Select the pre-filtered option to purchase the TW3712. The TW3712 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, Galileo E1, and BeiDou B1, as well as SBAS (WAAS, QZSS, EGNOS & MSAS).
The housing is a through-hole mount, weather-proofed enclosure for permanent installations. L-bracket or pipe mount adapters (part numbers 23-0040-0, 23-0065-0, respectively) are available for non-rooftop installation. (A 100 mm ground plane is recommended for non-roof-top installations.)
