  • RoHS compliant The TW2010 /TW2012 by Tallysman Wireless is a professional grade, magnet mount, GPS L1 antenna, speciall y designed for industrial, agricultural and military precision positioning and timing applications. The TW2010 /TW2012 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. The TW2012 also has a tight SAW pre -filter to provide unparalleled out -of-band signal rejection. It covers the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great c ircular polarized signal reception, multipath rejection and out of band signal rejection. The TW2010 is housed in a compact, industrial- grade weather-proof, magnet mount enclosure. Dimensions (mm) Dimensions (mm)
