Tallysman Wireless Inc. has released the TW2012, TW3012 & TW3032 GPS brickwall filtered antennas.

These antennas by Tallysman Wireless are professional grade, dual-filtered GPS L1 antennas, specially designed for precision positioning and timing applications in environments characterized by high L-Band RF fields (such as LighSquared interference). They feature 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.

The antennas cover the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and they offer out-of-band signal rejection and excellent axial ratio for improved signal reception and multipath rejection, the company said.

Applications:

• Anti-Jamming and Mission Critical GPS

• Precision Agriculture, Mining, and Construction
• Avionics
