Overview

The TW3470/TW3472 GLONASS/GPS Timing Antenna by Tallysman Wireless is a professional device that receives GLONASS L1, GPS L1 and SBAS (EGNOS/MSAS/WAAS) signals via the 1574 to 1606 MHz frequency bands. The antenna is chiefly conceived of for military applications requiring high precision and flexible mobility. It is highly regarded for its superior multipath and out-of-band signal rejection not to mention polarized circular signal reception.

Included in the unit is a low-noise amplifier with three-stages and a patch element with circular dual feed wideband. This ensures that axial ratio is constant over the whole frequency band.

An optional tight pre-filter (part number TW3472) guards against L-Band signal and high-level sub-harmonic saturation.

The TW3470/TW3472 antenna can be used in such applications as GPS/GLONASS fixed timing, high accuracy and mission critical global positioning, military and security, avionics, law enforcement and public safety, fleet management and asset tracking.
