TW2015 Embedded GPS L1 Antenna The TW2015 by Tallysman Wireless is a professional grade, embedded GPS L1 antenna, specially designed for industrial, agricultural and military precision positioning and timing applications. The TW2015 features a high performance custom tuned ceramic patch element, 15 KV ESD circuit protection, a high gain two-stage 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 TW2015 Dimensions (mm) circular polarized signal reception, multipath r ejection and out of band signal rejection. The TW2015 comes in a compact circular form factor with a built-in 50 mm diameter ground plane, and with a 15 cm RG174 cable. 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.
