Installation
Please observe the following warnings when installing the SpaceCom IP321 Maritime
Antenna with the Thuraya IP terminal:
WARNING:
•
Only use the included pole mount installation kit for permanent mounting of
the SpaceCom IP321 Maritime Antenna. The kit is designed for easy
installation and ensures proper drainage of the antenna and is able to
withstand the rigid mechanical stress encountered on a vessel.
•
Do not obstruct the drain holes at the bottom of the antenna (around the N-
connector) and at the bottom of the pole mount.
•
It is very important only to use the coaxial cables supplied for the installation
of the SpaceCom IP321 Maritime Antenna!! Using other cables can cause
degradation or loss of the satellite link.
5.1 Correct Placement of the Antenna
•
WARNING!! Avoid exposure to microwave radiation! Keep a safe minimum distance
of 1 meter around and above the antenna!
•
Keep a clear line of sight to the satellite. Preferably avoid all obstructions within 3
meters of the antenna. Obstructions less than 15cm in diameter can be ignored
beyond this distance. Otherwise the line-of-sight to the satellite may be obstructed
and the satellite link performance degraded.
•
Do not place the antenna close to interfering signal sources or receivers.
•
Vibration levels in a typical installation are usually much less than the specified
maximum values. It is however the responsibility of the installer to verify, that the
cited levels are not exceeded in any mode of operation of the vessel. In case of
abnormal vibration, typically at a resonance frequency, measures must be taken to
displace the resonance frequency or to dampen the vibration amplitude.
•
The external GPS antenna required for the Thuraya IP terminal should be placed at
least 1 meter from the SpaceCom IP321 Maritime Antenna and other interfering
signal sources or receivers (see the Thuraya IP manual for details on the external
GPS antenna).
5.2 Placement of Power Supply, AS03951
The Power Supply, AS03951 must be placed inside shielded from the elements.
5.3 Mechanical installations using the Pole Mount Kit
When installing a Maritime Antenna on a vessel the following important guidelines must be
followed in order to ensure that the antenna will operate trouble free throughout its service
life. Warranty will be void if guidelines are not followed.
The installation is based on a Pole Mount Kit AS-01518 supplied by SpaceCom.
Installation using the “Pole Mount Kit” is shown in Figure 3.
