of 
Antenna 
Unit 
Mounting considerations 
Install the antenna unit referring to the installation diagram on page D-3 or D-4. When 
selecting a mounting location for the antenna unit, keep in mind the following points: 
• 
Select a location out of the radar beam. The radar beam will obstruct or prevent reception 
of the GPS satellite signal. 
• 
The location should be well away from a VHF antenna. A GPS receiver is interfered by a 
harmonic wave of a VHF antenna. 
• 
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. 
• 
Mount the antenna unit as high as possible. Mounting the antenna unit as high as 
possible keeps it free of interfering objects and water spray, which can interrupt reception 
of GPS satellite signal if the water freezes. 
• 
If the antenna cable is to be passed through a hole which is not large enough to pass the 
connector, you may unfasten the connector with a needle nose pliers and 3/8-inch 
open-end wrench. Refasten it as shown in the figure below after running the cable 
through the hole.
