Installing the TracPhone terminal
Ground stud
To ensure that the terminal is grounded – also if the cable is disconnected
from the terminal, connect an extra ground wire to the ground stud on the
terminal. This ground wire must be a heavy wire or braid cable with a larger
diameter than the coax cable. The ground stud is located next to the power
switch.
Extending the ground plane
In some cases it may not be possible to access the hull and at the same time
place the terminal in a suitable place.
A way to insure good grounding and at the same time make it possible to
ground the coax cable - is to extend the ship ground plane by means of copper
foil. The maximum length of the foil is determined by the width of the foil.
Copper foil 5 cm wide: Max 50 cm
Copper foil 10 cm wide: Max 100 cm
Copper foil 20 cm wide: Max 200 cm
Ground stud
Note
The foil must be at least 0.1 mm thick.
