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.
The fitting in fig. 2 can be used at the top of a tube. Please note that it is necessary to mount the cable, and seal this
connection securely before the antenna and fitting are mounted on the tube.
