Surface Mount / Magnet / Adhesive
12 dB typ.
Many Options, Please Inquire
The TW4039 is a very low power, low gain, compact GNSS antenna covering the GPS L1, as well as SBAS (WAAS, EGNOS & MSAS).
- 5.5 mA current draw
- Invariant response, 2.5 to 16 VDC Supply
- Low Noise 3.3 dB typ.
- Axial ratio: 4 dB max.
- Low gain: 12dB typ.
- IP67 weather proof housing
- Longer battery life
- 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 that require protection against close-proximity 700MHz LTE and L-band transmitting antennas, the TW4039 is amongst the lowest power devices available, requiring a typical current consumption of just 5.5 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 TW4039 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4039 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.
The TW4039 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 TW4039 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
