Overview

Ideal for precision agriculture, mining, construction, and other applications where antenna precision matters, the TW2108 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).

The TW2108 features a customizable high performance, dual-feed, wide band patch element. Its Low Noise Amplifier (LNA) configuration provides a LNA for each feed, a mid section mid-section Surface Acoustic Wave (SAW) filter for the combined signal, followed by a final stage of LNA. This configuration provides ± 10MHz bandwidth centred on 1575.42 MHz.

The TW2108 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

Tallysman offers custom tuning services to optimize the performance of the TW2108 for any OEM installation environment.
