Antenna Unit

Refer to the antenna unit outline drawing at the back of this manual for mounting instructions.
When selecting a mounting location consider the following points:
• Select a location out of the radar and Inmarsat beams. Those beams will obstruct or prevent
reception of the GPS satellite signal.
• There should be no interfering object within the line-of-sight to the satellites. Objects within line-
of-sight to a satellite, for example, a mast, may block reception or prolong acquisition time.
• Locate the antenna well away from the antenna of a VHF radiotelephone to prevent interfer-
ence.
• Mount the antenna unit as high as possible. Mounting it this way keeps it free of interfering
objects and water spray, which can interrupt reception of GPS satellite signal if the water
freezes.
Note: If the antenna cable is to be passed through a hole in a bulkhead which is too small to pass
the connector, disassemble the connector with radio pincers and a monkey wrench. After passing
the cable through the hole assemble the connector as below.
