Tallysman TW1320/TW1322

Tallysman TW1322 Embedded Single Band GNSS Antenna (Pre-filtered)

The TW1322 GNSS antenna from Tallsyman is a high performance, low cost antenna covering GPS/QZSS L1 and SBAS (WAAS, EGNOS & MSAS).



Featuring a precisely tuned, single feed patch element that achieves 40% wider bandwidth than competitive antennas, the TW1322 supports 1 dB RHCP received power across the full frequency bandwidth covering GPS/QZSS L1 and GLONASS G1. Additionally, the TW1322 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

The TW1322 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

Tallysman offers custom tuning services to optimize the performance of the TW1322 for any OEM installation environment.
