Placing the Antenna
3.1 Obstructions
The antenna rotates 360° and down to –25° in pitch and roll to allow for
continuous pointing even during the worst sea states. Any obstructions within
this volume can cause signal degradation.
The amount of degradation depends on the size of the obstruction and the
distance from the antenna. As a rule of thumb any obstruction, which
subtends an angle of less than 3° at the antenna will have limited effect. The
table below gives a guideline for obstruction sizes, which will cause limited
degradation.
