3.1. Verify System Components
Before beginning it is critical that you inventory all system components. Refer to the appropriate packing list for your
Model antenna. Any discrepancies should be immediately reported to the Sea Tel service department so that a Service
Call may be filed and the required parts be shipped out.
3.2. Site Selection
Determine the optimum mounting location for the antenna radome assembly. Choosing the best mounting location
on vessels where there are few choice locations to choose from, is frequently a compromise. Below are some
considerations that should be taken as part of the Site Survey process.

1. Blockage: The antenna should be mounted where the antenna has a clear line-of-sight view to as much of
the sky as is practical. Choosing a location where masts or other structures do not block the satellite signal
from the dish as the boat turns will directly affect the antenna’s ability to locate and track the desired
satellite.
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 as will our antenna have less of an impact
on them.
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.
4. Bow or the Stern? Due to the violent G-forces exerted onto an antenna while the vessel’s BOW heaves versus
the relatively “cushioned” G-forces exerted onto an antenna at the stern of the vessel choosing the Stern
would be the ‘best’ option with all other factors being equal.
