Overview

Ideal for battery operated positioning, fleet management and asset tracking applications, the TW4327 single band GNSS antenna from Tallysman is amongst the lowest power devices available, requiring a typical current consumption of just 1.75 mA with constant characteristics over supply voltages from 2.5V to 16V – yet it still performs with an excellent noise figure.

Featuring a precisely tuned, single feed patch element that achieves 40% wider bandwidth than competitive antennas, the TW4327 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4327 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

The TW4327 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 TW4329 provides these additional benefits with an LNA pre-filter.
