TW2012 GPS Brickwall Filtered Antenna
The TW2012 by Tallysman™ is a professional grade, dual-filtered magnet mount, GPS L1 antenna, specially designed for precision positioning and timing applications in environments characterized by high L-Band RF fields.
The TW2012 features a precisely tuned ceramic patch element, a tight SAW pre-filter, a first LNA gain stage, a mid-section SAW filter and a final gain stage. It covers the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers unparalleled out-of-band signal rejection and excellent axial ratio for improved signal reception and multipath rejection.
The TW2012 is housed in a compact, industrial-grade weather-proof, magnet mount enclosure and a wide range of connectors.
