Details

Ideal for applications that require high precision positioning and timing in a small form factor, the TW1722 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, the TW1722 provides a truly circularly polarized response, with a typical axial ratio of less than 2dB over the full bandwidth.

The TW1722 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 TW1722 for any OEM installation environment.
