Overview

The TW1500 embedded Globalstar antenna from Tallysman is a low cost dual feed, passive Left Hand Circularly Polarised (LHCP) antenna specifically designed to maximise the performance of the Globalstar STU (Simplex Transmit Unit) modems.

The TW1500 has a wide-band dual-feed patch element with excellent axial ratio across the entire Globalstar bandwidth. Unlike single feed antennas, the TW1500 provides excellent multi-path rejection and a truly circular transmission response across the full bandwidth.

The embedded TW1500 includes a built-in 35 mm circular ground plane but best performance is obtained with this augmented with a local system ground plane or reflecting surface (a DC connection is not required).

Tallysman offers custom tuning services to optimize the performance of the TW1500 for any OEM installation environment.
