PLANNING
Avoiding interference Do not locate the antenna close to interfering signal sources, or in such a
position that the source (e.g. radar-antenna) radiates directly into the Sat-
urn antenna.
The Above Decks Equipment (ADE) should be separated as far as possible
from other transmitters, and preferably by at least 5 m from the antenna of
other communication or navigation equipment, such as the antenna of the
satellite navigator, the VHF antenna or radar equipment.
Compass safe distance For installation on British or Norwegian vessels, the antenna should be
located at a distance of at least 1.0 metres from the magnetic steering
compass. Be aware that requirements may vary from one country to
another.
Other precautions Do not place the antenna close to the funnel, as smoke deposits will then
eventually degrade antenna performance.
Regardless of the location chosen for the antenna, it should point forward
in parallel with the ship’s longitudinal axis when in the middle of its azimuth
range, which will correspond to zero degrees on the azimuth indicator. The
forward direction is indicated on the antenna radome with a heading mark
The antenna should be installed so that severe vibration and shock
are avoided.
If installed on top of a signal and radar mast, the mast must be
supported by stays.
The coaxial cable runs out from the antenna foot in the direction of
the heading mark.
