TW2743 can be switched between Iridium and  GNSS mode. This is done by changing the supply voltage between less than 5.5VDC for GNSS and more than 5.5VDC for Iridium modes.

Tallysman’s TW2743 maximises the performance of Iridium voice and data modems.

In both modes signals at the band edges remain truly circular.

When operating in GNSS mode, TW2743 features a high performance, dual feed, wide band patch element. Its Low Noise Amplifier (LNA) configuration provides a LNA for each feed, a mid section mid section Surface Acoustic Wave (SAW) filter for the combined signal, followed by a final stage of LNA. This configuration provides excellent axial ratio that is constant across the upper frequency band of GNSS.
