Obstructions should be below these
Figure 11 Inmarsat-C Antenna Mounting
If an obstruction such as a pole or a funnel is unavoidable, the
following guidelines apply:
According to IMO resolution 807 the distance to the obstruction
should be so large, that the obstruction only covers 2 degrees.
This means that the safe distance is:
Safe distance = 29 * Diameter of obstruction
Example:
Obstruction is a 4" pole. Diameter = 0.1 m. Safe distance is
29 * 0.1 m = 2.9 m
