2 Antenna and Cable Installation
Note: It is recommended that prior to installation, you pre-test the complete setup. This can be done on a bench or on
the deck of the boat. Connect all components to test if everything works fine. Doing so will familiarize the user how the
parts go together and guarantees it works fine prior to installation. Make sure the external antenna is located outside
and the Iridium GO! exec receives good signal reception for at least 5 minutes during this test before you proceed with
the installation. Maintain a separation of at least 20 cm (7.8 inches) from antenna during test.
Persons with Pacemakers:
• Should ALWAYS keep Iridium GO! exec and the antenna more than eight inches or twenty
centimeters from their pacemaker when the device is turned ON.
• Should turn Iridium GO! exec OFF immediately if there is any reason to suspect that interference
is taking place.
• Failure to heed this warning could result in serious injury or death.
The Iridium GO! exec device utilizes a negative ground system. When using a DC power source, such
as a car or boat, the power system must be a negative ground system. Do not use the device with
positive ground systems. Failure to properly ground the GO! exec could cause fire or could cause the
device to fail so that it is unavailable in an emergency situation, preventing or delaying an emergency
response. These hazards could cause serious injury or death.
Use the Iridium GO! exec device ONLY with Iridium supplied power accessories. Use of non-Iridium
supplied power accessories could result in exposing the device to excessive voltage, which could cause
fire or could cause the device to fail so that it is unavailable in an emergency situation, preventing or
delaying an emergency response. These hazards could cause serious injury or death.
Step 1)
Find a dry location for Iridium GO! exec inside the
vessel. Ensure that it is installed near a power source.
See the Iridium GO! exec Mounting Bracket Installation
on how to secure the Iridium GO! exec device in the
vessel. (Section 3 and 4)
Step 2)
Carefully consider the cable path to allow the cable length
for the exterior antenna to reach the Iridium GO! exec
device.
Step 3)
Bracket mounting: Install the Mast/Rail mounting
bracket within the 5 meter/16 feet proximity to a pole or
rail.
Vertical installation Horizontal installation
Antenna mounting:the antenna must not be
mounted at a location such that during radio
transmission, any person or persons can come closer
than the indicated minimum safe distance to the
antenna: 20 cm (7.8 inches). See Iridium GO! exec
User Manual for a discussion of exposure to radio
frequency (RF) energy.
Step 4)
Once the antenna mount bracket is securely in place:
1. Feed one end of the passive antenna cable through
the base of the bracket (A and B) then, feed the cable
through the Antenna base plate (C).
2. Screw the antenna base to the bracket (D).
Note: U ‐ Bolts can fit pole and rail with diameter 30 ‐
60mm.

Step 5)
Insert the satellite cable through the antenna
base
Step 6)
1. Connect the SAT antenna cable
connector (TNC-M) to the antenna
connector1 (TNC-F) and hand-
tight.
Step 7)
Screw the antenna base
to the antenna housing
using screws and Allen
key provided.
Ensure that you attach
the black rubber seal
(see step 4C above)
provided to the antenna
base plate.
Note:
1) Use of an external antenna will provide connectivity for the Iridium network and GPS reception.
2) To ensure maximum performance of the antenna and to maximize availability and reliability of service, the
position of the antenna must:
a) Have a clear view of the sky
b) Be clear and free of obstructions
c) Be clear of metal objects
d) Be located above and away from other transmitting
devices
e) Be securely affixed in location
f) Not be located indoors
g) Be installed in conjunction with a certified included
cable.

8
Step 8)
To minimize cables waving around, use the cable ties provided to fasten tight along
the pole or rail path and at both the antenna end and the Iridium GO! exec end.
Note:
1) Do not put stress on the cable. Ensure that the bend radius of the cable doesn’t go below 25mm slack (see 5.3
Passive Antenna Cable Physical Specifications).
2) When installing the antenna cables, follow these guidelines:
a. Route and restrain cables to prevent them from vibrating or moving under normal conditions which could
result in damage to the antenna or the coaxial cable connections.
b. Wherever the cables contact structures, protect the cables from chafing or abrasion. If a cable needs to be
bent or looped, avoid kinking it, and ensure that each bend radius follows the cable supplier limits.
c. Use coaxial sealant, shrink-wrap tubing, electrical tape, or another suitable product to seal all cable
connections appropriately to prevent moisture and corrosion damage from weather exposure. Mount all
antennas vertically and clear of nearby metal obstructions. Minimize horizontal obstructions as much as
possible because this can create areas of poor system coverage.
Step 9)
To protect the 15cm Iridium GO! exec cable adapter from damage,
cable ties shall be used at the Iridium GO! exec end to tighten the
satellite cable to any mounting equipment used. See illustration to the
right. It is important to make sure that the gap between the satellite
antenna cable connector and the Iridium GO! exec satellite connector is
close enough so that the Iridium GO! exec cable adapter is not stressed
at any point when connected to the Iridium GO! exec.
Step 10)
Connect the TNC end of the cable to Iridium GO! exec cable adapter, and then plug the Iridium GO! exec cable
adapter plug to the Iridium GO! exec Satellite connector.
The connectors for satellite on the device are located behind the cover found directly below the device antenna.

Note:
1) When an external antenna is connected, you may still raise the device internal antenna.
If the device’s “Power ON/OFF based on antenna lift” is enabled, this action turns the unit on and allows for
transmission over the Iridium network as well as acquiring location information using the connected external
antenna, while lowering the device antenna with the external antenna connected will not switch the device off.
To switch the device off with the external antenna connected, you need to use the power button on the device or
use the device’s Settings menu. Alternatively, with the device powered on and the device antenna in lowered
position, unplugging the external antenna will switch the device off.
If the device’s Setting “Automatically power on the device on charger connection” is enabled, unplugging the
device power supply will also switch off the device, while plugging the device to a power supply will switch the
device on.
2) Please use provided cable ties to secure the antenna cables to the mounting bracket.
3) The “LITE” kit does not include an external Global Navigation Satellite System (“GNSS”) Antenna and so will not
assist with providing location coordinates for SOS. Calls placed and messages sent using the LITE kit –
including SOS calls and messages – will not include accurate location services.
While the Iridium GO! exec device itself does have an antenna with GNSS capabilities, using the internal
antenna indoors will reduce reception and will likely result in poor or no signal reception for all purposes,
including SOS functionality. Location services will not be accurate and may show no location found. Calls –
including SOS calls – will still go through, but the app or the Iridium GO! exec device will be unable to accurately
display the location coordinates.
4) To allow the Iridium GO! exec device to use the internal GNSS antenna, the device's Settings menu MUST be
updated. On the LCD choose “Settings” then “GNSS Antenna Config” then “Internal”. This will force the device
to always use the internal GNSS antenna. Note that the device FW version must be 1.0.6 or higher to support
this feature.
3 Using the LITE Kit
To use the LITE kit, the Iridium GO! exec device firmware must be version 1.0.6 or higher – updates are
available via the most recent Iridium GO! exec App release on the Apple App Store and Google Play. Users just
need to download the latest version, connect to the Iridium GO! exec and follow firmware upgrade prompts on
the app screen.
Note: Users will need to change their device’s “GNSS Antenna Config” setting to “Internal” to use internal
GNSS with the single mode antenna is connected.
User will see the following options:
1) Auto:
•Devices will be set to “Auto” out of the box.
•Auto allows users to switch to an external GNSS antenna (for example, the dual mode antenna) when
it detects one is connected.
•This option also allows the device to switch back to internal GNSS when it detects the external iridium
antenna has been removed.
Note: If Auto is used with the single mode antenna, the device will not use internal GNSS and assume an
external antenna is equipped, and therefore continue searching for it.

10
2) Internal:
•This option overrides the auto/default setting and forces the device to always use internal GNSS even
if it detects an external antenna.
•This option must be selected when using the single mode antenna.
3) External:
•This option overrides the Auto/default setting and forces the device to only use the external GNSS antenna,
regardless of whether one is equipped.
•This option can be used with Iridium’s Premium Dual Mode Antenna, but it is not recommended as the
user will need to return to Auto once they disconnect the external antenna.
This LITE antenna kit does not support location services. To engage location services –
including SOS emergency calls and messages – the Iridium GO! exec should be used outdoors
with a view of the sky, and the device’s GNSS Antenna Config should be set to
“internal” setting.
Failure to do so could cause location services to fail or produce inaccurate results and, in the
case of an emergency, could prevent or delay an emergency response. This could cause
serious injury or death.
Do not leave power and antenna ports uncovered. Open power cover only for as long as
recharging is required, and open antenna cover only when actively using the external antenna.
Leaving the covers open allows moisture and water vapor to enter the device which in turn
could lead to corrosion and damage to the device. This could cause fire or could cause the
device to fail so that it is unavailable in an emergency situation, preventing or delaying an
emergency response. These hazards could cause serious injury or death.
