The TW4327 is a very low power, compact GNSS antenna covering the GPS L1, GLONASS G1, as well as SBAS (WAAS, EGNOS & MSAS).


  • Very low power consumption
  • 40% wider bandwidth, small footprint
  • Axial ratio: 6 dB Typ. (GPS & GLONASS)
  • Low noise LNA: 1 dB
  • High rejection mid-section SAW filter
  • Wide voltage input range: 2.5 to 16 VDC
  • IP67 weather proof housing


  • 1dB Bandwidth Includes GPS-L1 & GLONASS
  • Excellent multipath rejection
  • Improved GNSS reliability
  • Excellent signal to noise ratio
  • RoHS compliant
  • Ideal for harsh environments
  • Excellent out of band signal rejection


Ideal for battery operated positioning and fleet management & asset tracking applications, the TW4327 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.

LNA Pre-filter Available
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. Click here to learn more about the TW4329.
