Necessary tools and equipment
We assume that you are equipped with a standard set of tools. This tool set must
comprise the normal tools for electronic and electromechanical tasks. This includes
different screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each
tool must be provided in various sizes. We recommend that all tools are demagnetized to
protect your equipment.
We recommend a 21 Ncm torque wrench to tighten the antenna connectors.
Unless otherwise stated, all mounting hardware (such as bolts, nuts, washers, screws
etc.) referred to in this document is to be supplied by the customer or the shipyard.
An external computer is required for configuration of the Radio Unit through a web
interface. You also need a computer if you want to change the configuration later.
Radio Unit location
Correct location of the Radio Unit is important for the system performance. Consider
these factors when installing the unit.
• Mount the Radio Unit in such a way that external cooling through the bottom
aluminium plate is possible.
• Do not mount on heat-insulating surfaces.
• Use a stable power source with correct voltage.Maximum power consumption is 25 W.

Radio Unit power requirements
The Radio Unit must be powered by a dedicated power supply.
Arranging the antennas
The four antennas constitute the antenna array. They can be arranged in a position that
works best for your installation. There are three suggested ways to arrange the antenna
array.
As the antenna array is self-calibrating, the antenna arrangement is flexible. You can
safely select which of the three arrangements will best suit your operation.
Quadratic array
Arrange the antennas in a square with 25 mm space between the antennas.
