2.1.4 Obstruction

The mounting position of the antenna unit especially its line-of-sight are possibly obstructed

by any large obstacle in a vessel or ship. This will result in the degradation of the satellite

signal. It is very important to choose the ideal installation site on the upper deck to minimise

the satellite blocking.

Examples of the large obstacles are:

 Upper Deck and funnel of ship

 VSAT with its radome

 Large mechanical structure mounting of radars
