Possible Antenna Radome Assembly mounting locations
1. Installation
Installation of your ST-14(D/E/M) Antenna system must be accomplished by or under the supervision of an
authorized Sea Tel dealer for the Sea Tel Limited Warranty to be valid and in force.
Good planning of the
installation will provide the best results. Below is some guidance on issues that are important to consider when planning the
installation.
Planning is the key to a good installation. Read the installation information below thoroughly before beginning the actual
installation. Then review your plan to adjust for any details that may have been overlooked.
A full scale Installation Template (drawing 126355) has been provided to locate the cutout areas and mounting holes for the
antenna radome and for the antenna control panel. The radome template section of the drawing includes the outer perimeter
of the radome base so you can insure that the radome will fit in the area chosen.
1.1. Site Selection and Cable Routing Path
The best mounting location for the antenna radome assembly is 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 boat 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 Coastal Series antenna. The further away the Coastal antenna is from
these other antennas, the less
impact their operation will have on
it.
3. The antenna radome assembly
should be rigidly mounted to the
boat. If necessary, reinforce the
mounting area to assure that it
does not flex due to the boat
motion or vibration.
Choosing the best mounting location on
smaller boats, where there are fewer possible
locations to choose from, is frequently a
compromise. The Figure shown to the right
is provided to make some location
comparisons. The “poor” location is poor
because over half of the antenna’s viewable
sky is blocked by the overhang above it. The
“better” location has fewer blockages, but
the upper deck and the mast will cause some
blockage when the antenna is at lower
elevations. The “best” location has no
blockage from raised platforms, mast or the
body of the radar.
If enclosed in a cabinet or panel, assure that there is adequate airflow to prevent from over-heating and provide forced
airflow if needed.
