TW3710 /TW3712 Multi-Constellation Fixed Mount Ant 返回列表页

The TW3710 /TW3712 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. Both antennas feature 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 along with a superb phase linear response and tight phase centre variation providing performance normally associated with much higher priced antennas. The TW3712 has a pre-filter to protect against front end saturation by strong near frequency or harmonic signals. The antennas are housed in a through-hole mount, weatherproof 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.
