Determine the optimum mounting location for the antenna radome assembly. It should be
installed where:
1. The antenna has a clear line-of-sight view to as much of the sky as is practical. Choose
a location where masts or other structures do not block the satellite signal from the dish
as the vessel turns.
2. The antenna is at least 5 feet away from other transmitting antennas (HF, VHF and
radar) that may generate signals that may interfere with the antenna. The further away
the antenna is from these other antennas, the less impact their operation will have on it.
3. Direct radiation into the antenna from vessels radar, especially high power surveillance
radar arrays, is minimized. The radome should be as far away from the vessels Radar as
possible and should NOT be mounted on the same plane as the vessels Radar.
4. The antenna radome assembly should be rigidly mounted to the vessel. If necessary,
reinforce the mounting area to assure that it does not flex due to the vessel motion or
vibration.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best”
compromise between the various considerations.
Figure 2-2 Selecting the location
Perform a through site inspection on the roof for the antenna to be mounted.
1. The antenna must have a clear view of the sky and the horizon at all
the directions to avoid blockage of the satellite signal.
2. The antenna should be on the top of the vehicle.
