Mounting considerations for the antenna
When looking for a place to mount the SAILOR Fleet One antenna, make the following
considerations:
• Do not place the antenna close to large objects that may block the signal. Place the
antenna with free line of sight in all directions to ensure proper reception of the satellite
signal.
• Place the antenna in such a way that persons are not exposed to radiation from the
antenna. Keep the minimum safety distance. See Safety summary on page iii.
• Do not place the antenna within range of other equipment that can interfere with the
SAILOR Fleet One.
• Do not place the antenna close to a funnel, as smoke deposits are corrosive. Furthermore,
deposits on the radome can degrade performance.
• Do not block the drainage gasket in the bottom centre of the antenna. Leave space below
the antenna to allow any water to escape.
The following sections describe the details for the mounting considerations.
Obstructions
The antenna rotates 360° and down to -60° in pitch and roll, to allow for continuous pointing
even in heavy sea conditions. Any objects within this field can cause signal degradation.
The amount of degradation depends on the size of the object and the distance from the
antenna. As a rule of thumb any object that covers an angle of less than 3° at the antenna has
limited effect. The table below gives a guideline for the distance and maximum size of blocking
objects in order to avoid degradation.
Distance of object Maximum size of object
3m 16cm
5m 26cm
10 m 52 cm
20 m 104 cm
