9. INSTALLATION

9.2 Installation of Antenna Unit

Mounting considerations

Install the antenna unit referring to the an-

tenna installation diagram at the end of this

manual. When selecting a mounting loca-

tion for the antenna unit, keep in mind the

following points:

• Do not shorten the antenna cable.

• Select a location out of the radar beam.

The radar beam will obstruct or prevent

reception of the GPS signal.

•

The location should be well away from a

VHF/UHF antenna. A GPS receiver is in-

terfered by a harmonic wave of a VHF/

UHF 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 recep-

tion or prolong acquisition time.

• Mount the antenna unit as high as pos-

sible. Mounting the antenna unit as high

as possible keeps it free of interfering

objects and water spray, which can in-

terrupt reception of GPS satellite signal

if the water freezes.

• The length of the whip antenna for the

GPA-018 (for GP-36) should be no

longer than 1.2 meter to prevent antenna

damage. Do not use a 2.5 meter whip

antenna.

• If the antenna cable is to be passed

through a hole which is not large enough

to pass the connector, you may unfas-

ten the connector with a needle nose

pliers and 3/8-inch open-end wrench.

Refasten it as shown in Figure 9-2, after

running the cable through the hole.

9.1 Installation of Display Unit

Mounting considerations

The display unit can be installed on a table-

top, on the overhead, or in a panel (optional

flush mounting kit required). Refer to the

outline drawings at the end of this manual

for installation instructions. When selecting

a mounting location, keep in mind the fol-

lowing points:

• Locate the unit away from exhaust pipes

and vents.

• The mounting location should be well

ventilated.

• Mount the unit where shock and vibra-

tion are minimal.

• Locate the unit away from equipment

which generates electromagnetic fields

such as a motor or generator.

• Allow sufficient maintenance space at

the sides and rear of the unit and leave

sufficient slack in cables, to facilitate

maintenance and servicing.

• Observe the following compass safe dis-

tances to prevent deviation of a magnetic

compass. Standard compass, 0.5 m,

Steering compass, 0.3 m.
