TW3012 GPS L1, Brickwall Pre-Filtered Antenna

The Tallysman TW3012 from Calian is a professional grade, highly filtered permanent mount, GPS L1 antenna, specially designed for precision positioning and timing applications in environments characterized by high L-Band RF fields.

 

The TW3012 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 TW3012 is housed in a permanent mount industrial-grade weather-proof enclosure, and comes with a TNC Jack (female) connector.
