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
With the understanding of the large obstacle, it helps in the decision of the installation site
with the reduction of the physical obstruction.
