TW1027 Embedded Single Band GNSS Antenna

Tallysman TW1027 Embedded Single Band GNSS Antenna

The TW1027 embedded single band GNSS antenna from Tallysman supports coverage for GPS/QZSS L1, as well as SBAS (WAAS, EGNOS & MSAS).



Ideal for battery operated positioning and fleet management and asset tracking applications, the TW1027 embedded single band GNSS antenna 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 TW1027 supports 1 dB RHCP received power across the full frequency. Additionally, the TW1027 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

Tallysman offers custom tuning services to optimize the performance of the TW1027 for any OEM installation environment.
