Product Description

TW2405 Embedded GPS/GLONASS Antenna

The TW2405 by Tallysman Wireless is a professional grade embedded GNSS antenna covering the GPS L1, GLONASS L1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It is especially designed for precision industrial, agricultural and military OEM applications. The TW2405 offers a truly circular polarized response across the full bandwidth providing high multi-path signal rejection resulting in higher accuracy of position and time.

The TW2405 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band.

The TW2405 comes in a compact circular form factor with a built-in 50 mm diameter ground plane.
