TW2010 Magnet Mount GPS L1 Antenna The TW2010 by Tallysman Wireless is a professional grade, magnet mount, GPS L1 antenna, specially designed for industrial, agricultural and military precision positioning and timing applications. The TW2010 features a high performance custom tuned ceramic patch element, 15 KV ESD circuit protection, a high gain two-stage Dimensions (mm) p/n 32-2010-0 low noise amplifier (LNA) with a mid section high rejection SAW filter. It covers the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception, multipath rej ection and out of band signal rejection. The TW2010 is housed in a compact, industrial- grade weather-proof, magnet mount enclosure. Dimensions (mm) p/n 32-2010-7 Applications High Accuracy & Mission Critical GPS Precision Agriculture, Mining & Construction Military & Security Avionics Law Enforcement & Public Safety Fleet Management & Asset Tracking Features Benefits Very low noise LNA: 1 dB Great multipath rejection Great axial ratio: <4dB at Zenith Increase system accuracy High rejection SAW filter Excellent signal to noise ratio High gain: 28 dB typ.
