Tallysman TW4320 Single Band GNSS Antenna

Tallysman TW4320 Single Band GNSS Antenna

The TW4320 single band GNSS antenna from Tallysman is a compact, commercial grade antenna covering GPS/QZSS L1, GLONASS G1 and SBAS (WAAS/EGNOS/MSAS).



Featuring a precisely tuned, single feed patch element that achieves 40% wider bandwidth than competitive antennas, the TW4320 single band GNSS antenna from Tallysman supports 1 dB RHCP received power across the full frequency. Additionally, the TW4320 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

The TW4320 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.

If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW4322 provides these additional benefits with an LNA pre-filter.
