2.10 Installation of the Antenna
One of the advantages of this equipment is the easy-to-
handle, lightweight and rugged antenna. Because the
IRIDIUM ® system is characterised by a good link margin,
the antenna is a passive quadrifillar helix type, requiring
no external power supply and consisting of only nonmoving
parts.
The following figures show the antenna and the two
different mounting accessories available:
The mounting bracket in fig. 1 can be used in two different
ways - mounted on either a rail or a pole.
Important!
To comply with FCC RF exposure regulations, the antenna
must be installed in a location providing a minimum RF
Radiation Safety Distance of 0.61m (2 feet).
Important!
It is important that the antenna cable used has a maximum loss of 3dB @ 1.6GHz between antenna and transceiver.
This antenna cable must be in one piece. Neglecting this will reduce the overall receiving/transmitting performance
at sea. If installation is not carried out in accordance with these guidelines, it will void the warranty of the product.
