Overview

The TW4029 is a very low power, compact GNSS antenna covering the GPS L1, as well as SBAS (WAAS, EGNOS & MSAS).

Features

  • Nominal 2 mA current draw
  • Invariant response, 2.5 to 16 VDC Supply
  • Low Noise 3.5dB typ.
  • Axial ratio: 4 dB max.
  • High gain: 21 dB typ.
  • IP67 weather proof housing

Benefits

  • Longer battery life
  • Excellent signal to noise ratio
  • RoHS compliant
  • Ideal for harsh environments
  • Excellent out of band signal rejection

Details

Ideal for battery operated positioning and fleet management & asset tracking applications, the TW4029 is amongst the lowest power devices available, requiring a typical current consumption of just 2 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 TW4029 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4029 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

The TW4029 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

The TW4029 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
