Overview

The wideband dual feed patch element in the TW1500 has an excellent axial ratio across the entire Globalstar bandwidth. Unlike single feed antennas, the TW1500 provides excellent multipath rejection and a truly circular transmission response across the Globalstar band.

The 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 (DC connection not required).

OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules.
