It is recommended that, prior to installation, you pre-test the complete setup. This can be done on a bench at home or on the boat's deck away from the harbour 1NM to avoid the radio frequency interference of marinas and port authorities. Connect all the components to test everything works.

The external antenna needs to be mounted outside where it has the best possible view of the sky and horizon with minimal obstruction to get the best Iridium signal. It must also be clear of metal objects, above and away from other transmitting devices.

Iridium has been very careful to specify the cable length for the LMR 400 Iridium GO! exec antenna cable at its maximum of 5 metres / 16 feet. Carefully consider the cable path and where the GO! exec can be mounted in a dry location, inside the vessel, close to a power source.

PredictWind recommends installing the antenna on the pushpit of your vessel. If on a yacht, we recommend installing the antenna near the pushpit area, above solar panels and not on the yacht mast.

The thick, black coaxial cable is not designed to be bent around any hard corners; it has a 25mm minimum radius.

With the GO! exec and external antenna well mounted, you can use any length of ethernet cable to connect the DataHub to the Iridium GO! exec. The DataHub will become the Wi-Fi hotspot to which you can connect all your devices.

Avoid mounting the external antenna near any radar that is 4KW or higher. If mounting near a radar, please mount the external antenna above the radar.

VHF antennas will not cause signal interference, but they mustn't be obstructing the Iridium GO! antenna's view of the sky/horizon.

If you have a GPS receiver, it is important to mount the external antenna with at least a 1-meter separation between the two.

Avoid mounting the antenna within 2 meters / 6.5 feet of a wind generator, as it may cause electrical interference.

The antenna must not be mounted in a location any person would be within the minimum safe distance of 20cm / 8 inches during radio transmission.

With the antenna mount bracket securely in place, refer to the image below:

Insert the satellite cable through the antenna base.

Connect the SAT antenna cable connector (TNC-M) to the antenna connector1 (TNC-F) and hand-tighten it.

Screw the antenna base to the antenna housing using screws and the Allen key provided.

To prevent the cable from moving, use the cable ties provided to fasten it tight along the pole or rail path at both the antenna end and Iridium GO! exec end.

Protect the 15cm Iridium GO! exec cable adaptor from damage using cable ties to secure it at the GO! exec end and tighten the satellite cable to any mounting equipment used. It is essential to make sure the gap between the cable connector and the satellite connector is close enough so that the cable adaptor is not stressed at any point when connected.

The external satellite antenna connector is found directly next to the device's internal antenna.

Be careful when connecting the GO! exec cable adaptor to the GO! exec Ext. Satellite Connector as it is very delicate.
