## TW3010/TW3012 Permanent Mount GPS L1 Antenna 

The TW3010/TW3012 by Tallysman is a professional grade, permanent mount GPS L1 antenna, specially designed for precision tracking and timing applications. 

The TW3010/TW3012 features a custom high performance, wide band patch element, a 30dB gain LNA stage and a high rejection out-of-band SAW filter. The TW3012 includes a tight SAW pre-filter to provide strong protection against out-of-band signals.  It provides ±10MHz bandwidth centred on 1575.42 MHz and covers the GPS L1, and SBAS (WAAS/EGNOS/MSAS) signals.  It provides great axial ratio, excellent circular polarized signal reception, great multipath rejection and great out-of-band signal rejection. 

TW3010/TW3012 Dimensions (mm) Flat Radome shown.  Conical Radome also available 

The TW3010/TW3012 is housed in a permanent mount industrial-grade weather-proof enclosure. Optional Mounts of an L Bracket (PN 23-0040-0) or Pipe Mounts (PN 23-0065-0) are available.
