Ensure that the
channel is filled
with silicon to
provide a seal when
gasket is in place.
5. Attach the four threaded pins to the antenna.
6. Peel the plastic off the gasket.
7. Place antenna in final position.
8. Attach the four nuts to
the threaded rod. Do not
overtighten.
9. Attach to instrument, then
secure the cable at regular
intervals.
2 Choosing a suitable location for the antenna
Mount the antenna with a good view of the sky and
horizon. The view should not be blocked by large
parts of the superstructure.
The unit can be under glass, perspex, fibreglass
or fabric, but not under metal or wood.
Mount the antenna away from any source of
electrical signals or noise. Do not mount the
antenna within 3 m (10 ft) of a radio transmitter
antenna or within 0.5 m (20") of the plane of a
radar antenna.
Do not fit the antenna too high, such as up a mast, or boat rocking will cause errors in speed
and bearing.
Do not mount the antenna where it can be
used as a hand hold, where it will interfere with
the operation of the boat or where it might be
submerged.
Mount the antenna within the connection range
of the cable in it's final secured position, keeping
the cable away from sources of electrical signals
or noise and ensuring the cable is not pinched
or crushed.
3-1 Surface mounting
Select a suitable location which allows access for affixing nuts and has a suitable mounting surface. Avoid
high traffic areas where the antenna may be a tripping hazard.
Ensure that any holes made are in a safe position and will not weaken the boat’s structure. If in doubt,
consult a qualified boat builder.
3 Mounting
There are two mounting options:
Pole mounted Surface mounted
1. Clean the surface where the antenna will be
mounted.
2. Peel the back off one
side of the gasket and
stick the gasket in the
final mounting position.
3. Using the gasket as
a template, drill four
4 mm (5/32") holes.
4. The cable may
either pass through the surface the antenna
is mounted on, or exit the side of the
antenna:
4A For GPS 100 if
passing cable through
the surface, drill an 18 mm
(23/32") hole for the
connector.
4B If exiting the side of the
antenna, remove three
plastic tabs, then seal
cable into place with
silicon.
