Overview

The TW1027 is a very low power, compact GNSS antenna covering the GPS L1, frequency band. This antenna features an LNA with a nominal current consumption of just 2mA, with constant performance from 2.5V to 15V supply voltage, and includes protection against close proximity L-band transmitting antennas such as Iridium and Globalstar.

The TW1027 has amongst the lowest power consumption available, yet still provides 21dB nominal gain and an excellent Noise Figure. The TW1027 patch has 40% wider bandwidth for better axial ratio and has 15 KV ESD circuit protection. The LNA has a +/- 10MHz bandwidth that covers the full GPS L1 signal plus the SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz).

The TW1027 is available with a variety of connectors and custom cable lengths.

It is highly recommended to take advantage of Tallysman’s custom tuning service to ensure optimal performance of this antenna in your housing and with your ground plane.
