Tallysman TW3042 GPS Brickwall Pre-Filtered Antenna

The Tallysman Wireless TW3042 is a professional grade, high gain, pre-filtered permanent mount, GPS L1 antenna, specially designed for precision positioning and timing applications in environments characterized by high L-Band RF fields.



The TW3042 features a precisely tuned ceramic patch element, a tight band-pass SAW pre-filter, a first LNA gain stage, an in line SAW filter, followed by a two stage amplifier. 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 TW3042 is housed in a permanent mount industrial-grade weather-proof enclosure that is available in dark gray or white and comes with a TNC Jack (female) connector. An L-bracket for pole mount is available.
