TW3032 GPS Brickwall Timing Antenna
This antenna has been replaced by the TW3012. Existing customers can continue to order this antenna with the same part number. New customers, please order the TW3012 with the appropriate radome selection.
The TW3032 by Tallysman Wireless is a professional grade, dual-filtered permanent mount GPS L1 antenna, specially designed for precision positioning and timing applications in environments characterized by high L-Band RF fields.
The TW3032 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 TW3032 is housed in a compact, industrial-grade weather-proof, domed shaped enclosure. Its radome is available in dark gray or white and two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0)
