Details

Ideal for applications that require high precision positioning and timing in a small form factor, the TW1421 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 TW1421 provides excellent axial ratio and cross-polarization rejection across the full frequency band.

Tallysman offers custom tuning services to optimize the performance of the TW1421 for any OEM installation environment.

LNA Pre-filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW1422 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW1422.
