Description
Tallysman TW3710 GPS/GLONASS/BeiDou/Galileo Antenna employs Tallysman’s unique Accutenna™ technology covering the BeiDou B1, Galileo E1, GPS L1, GLONASS G1 and SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1557 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. It is especially suitable for high accuracy applications, and also offers high out of band signal rejection.
The TW3710 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.
The TW3710 is housed in a through-hole mount, weather-proof 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 100mm ground plane is recommended for non-roof-top installations.
