TW1422 Accutenna® Pre-Filtered Embedded Single-Band GNSS Antenna

Description

Ideal for applications that require high precision positioning and timing in a small form factor, the TW1422 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).

Featuring a compact 25mm dual-feed, wideband patch element with a two-stage Low Noise Amplifier (LNA), the TW1422 provides excellent axial ratio and cross-polarization rejection across the full frequency band.

The TW1422 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

Calian offers custom tuning services to optimize the performance of the TW1422 for any OEM installation environment.
