11 Installation
11.1 Inspection
Inspect the ADL120 and all supplied parts for condition and completeness. Verify on
our website that you have the most up to date version of this installation manual.
11.2 Iridium Antenna
The device uses an Iridium antenna to communicate with the Iridium satellite
network. This antenna is also used by the build-in GPS receiver. If an outside
mounted Iridium antenna is available, this will represent the best solution. If such an
antenna is not available we recommend using an antenna mounted on the instrument
glareshield. This will provide good reception at a much lower cost than an outside
antenna installation.
The antenna will be connected to the device using a SMA connector. If your antenna
does not come with such a connecter it must be crimped on the cable.
11.2.1 Glareshield antenna installation
In the case of a glareshield installation we recommend the
Iridium SYN7391-C
antenna. This antenna has been tested with good results and the antenna does not
incorporate any magnetic mount which could deviate the magnetic compass. In
general you should try to place the antenna as far forward as possible in order to give
it the best panoramic opening to the sky possible.
Figure 5 shows such a glareshield installation of the SYN7391-C antenna.

11.2.2 External antenna installation
We recommend the use of the S67-1575-109 antenna manufactured by Sensor
Systems Inc. Before attempting the installation of any outside antenna and drilling
any holes in the hull, please make sure you have the required documentation and
certification. For any certified aircraft a minor or even a major change will be
required.
