Ideal for applications that require high precision positioning and timing in a small form factor, the TW1430 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 TW1430 provides excellent axial ratio and cross-polarization rejection across the full frequency band.

Tallysman offers custom tuning services to optimize the performance of the TW1430 for any OEM installation environment.

The TW1430 is a higher gain version of the TW1421 and is designed to meet the specifications of receivers requiring the higher gain, such as the Trimble BD9xx family of receivers.
