Installing the Antenna
Planning the Antenna Installation
The fixed site antenna system consists of a fixed mount antenna and a coaxial cable
system that connects the antenna to the RST310.
The antenna system is suitable for both marine and terrestrial applications and is
designed to meet Iridium System performance requirements when installed
according to the instructions in this guide.
The following figure shows a typical terrestrial application:
The Fixed Site Antenna is an antenna contained within a weatherproof housing. It is
intended to be mast-mounted without any type of ground plane. For proper
performance in the Iridium System:
•
The antenna must have a clear line to the sky from the horizon up
•
Mount the antenna vertically
•
Position the antenna so that it is reasonably clear of nearby metal obstructions
•
Minimize horizontal obstructions as much as possible because they can create
areas of poor system coverage. These areas of poor coverage can decrease
or possibly eliminate the user’s ability to operate the RST310 with
predictability.
A specialised coaxial cable system is required to connect the Fixed Mast Antenna
and RST310. This cable system is offered as an option to the Fixed Site Antenna.
To minimize the loss of radio signal from the antenna to the RST310, the coaxial
cable system between the antenna and the other component should be less than
3dB including connector loss.
