No. Unfortunately, an existing Iridium GO! external antenna cannot be used with the new GO exec. The GO exec external antenna is different. While they do look similar and use the same LMR400 cable, the connectors are different, and the GO exec antenna is spec'd for the Certus 100 service, so it has different internals.

The LMR400 cable for the GO exec can only be 5 meters long, as anything longer than 5 meters will result in significant signal loss and unacceptable performance.

The short thin connection cable that connects the GO exec to the LMR 400 cable differs from the Iridium GO! short thin connection cable.

The GO exec antenna has a TNC female at the base of the unit, where the Iridium GO! antenna base has an N type female connector.

To ensure a reliable and consistent connection, PredictWind recommends customers purchase and install the Iridium GO! exec Single Mode Antenna LITE Kit (No GNSS). This has one Iridium satellite antenna only and does not include an additional GPS antenna.

This antenna is included as part of the PredictWind Iridium GO! exec™ Complete Package, or, if you already have a GO exec you can buy this separately here.

Iridium also offers a Premium Dual Mode Antenna Kit (with GNSS), which includes a GPS antenna. PredictWind designed and recommends the DataHub for the GO exec to enable automatic and reliable GPS tracking.
