Disclaimer
What you need to consider
The antenna is a critical element in an HF communications
system. Correct installation of the antenna provides efficient
operation over the frequency range of the transceiver. A good
installation ensures the antenna provides optimum output
power during transmission and clear reception of weak
signals.
When installing the antenna you must consider:
• the location and mounting of the antenna
• how to provide a good earth plane for the antenna
• the routing of the coaxial and control cable
WARNING
The antenna should be installed by a suitably-
qualified technician, to the relevant standards
and approvals.
WARNING
While the following instructions are intended to
assist with installation, it is the purchaser’s
responsibility to ensure that the antenna is
installed with due regard to pedestrian and
vehicle-occupant safety, particularly in the
event of a vehicle accident. Codan accepts no
responsibility or liability in the event of injury
to pedestrians or vehicle occupants or any other
damage due to insecure or otherwise unsafe or
inappropriate installation of the antenna.

Installing the antenna
Automatic Tuning Whip Antenna 9350 Installation Handbook 9
Location
To obtain optimal radiation efficiency from your antenna, and
optimal reception at your antenna, it must be mounted in a
location that:
• is clear of surrounding body work
• supports a good earth plane
• supports the RF earthing required for correct tuning and
loading
• does not obscure the driver’s vision
• does not obscure number plates or vehicle lights
• does not interfere with engine or car openings
• allows for best radiation (open and clear of all metal
obstructions)
• clears electric power lines, overhanging trees, bridges etc
• does not breach vehicle-licensing regulations
A mounted antenna must have:
• a strong anchorage for the base of the antenna
• a sound electrical connection to the vehicle chassis

Installing the antenna
10 Automatic Tuning Whip Antenna 9350 Installation Handbook
Possible mounting locations that provide good electrical
performance of the 9350 Automatic Tuning Whip Antenna are
shown in the following photographs.

Installing the antenna
Automatic Tuning Whip Antenna 9350 Installation Handbook 11
Figure 6: Front-mount location on off-road vehicle
Mounting bracket
The antenna must be mounted on a sturdy metal plate (10 mm
(½ in) thick), strengthened by a support bracket on at least one
side. The mounting bracket and fixing should be able to
withstand any vibrations induced from the vehicle travelling
over an off-road surface. A strong metal plate that is large
enough to support the antenna will also provide efficient
earthing. The plate must have a 17 mm (0.67 in) hole to accept
the mounting screw.
The mounting bracket should be located such that the top half
of the antenna tuner shroud, or more, sits above any adjacent
horizontal metal plane on the vehicle (for example, a trunk lid,
hood, or roof).
The bracket should be located so that any flexing of the
antenna assembly does not damage the panels of the vehicle.
CAUTION
If the antenna is front-mounted, it should be
mounted on the side opposite to the driving
position.
NOTE You should consider any overall height
restrictions that are relevant to your vehicle.

Installing the antenna
12 Automatic Tuning Whip Antenna 9350 Installation Handbook
The installed antenna should enable easy access to the
connectors.
Earthing
Most mobile antennas are considerably shorter than a quarter
wavelength at HF, and can exhibit an extremely low radiation
resistance. Consequently, their efficiency is reduced compared
with the quarter-wave radiator that they represent. This can be
improved by good installation practices, and most importantly,
by the provision of a low-impedance earth return for the
antenna.
Due to the relatively poor earth plane surrounding a mobile
HF antenna, best use should be made of what is available. A
reduction in any losses can increase antenna current and
radiation. This can often be achieved by providing a good
earth connection from the base of the antenna to nearby
bodywork. An earth strap is provided for this. Connections to
the vehicle chassis are not as effective because many 4WD
vehicles have insulating mountings from body to chassis.
A strong metal plate that is large enough to support the
antenna will provide efficient earthing. The plate should be
welded to the chassis or some other part of the vehicle’s frame.
The mounting bracket and plate must be free of rust and paint
to allow metal-to-metal contact between the base of the
antenna and the mounting bracket. This electrical bond is the
basis for effective RF earthing. RF currents flow on the
conductor surface, therefore good RF earthing requires
conductors with large surface areas.
NOTE The shroud over the antenna tuner can flex up to
150 mm (6 in) without damage to the shroud.
NOTE Conductive grease should be used on the
touching surfaces to help prevent corrosion.

Installing the antenna
Automatic Tuning Whip Antenna 9350 Installation Handbook 13
The RF earth differs from the DC earth required by the battery
and the vehicle’s electrics. For more information on power
supply factors and earthing the transceiver see the Reference
Manual provided with the transceiver.
Cabling
The coaxial cable between the antenna and the transceiver
should be installed as far as possible from other vehicle
wiring, especially high-tension ignition wiring or the engine
management computer.
The cabling must be in a position that:
• is away from the driver’s feet
• is secured and concealed as much as possible
• ensures the control and coaxial cables are separated from
the DC power cable by at least 200 mm (8 in) (except
over short distances, for example, to pass through the
same hole in a bulkhead)
• is secured behind protective metalwork (only if the
cables run under the vehicle)
Keep cables in the engine compartment away from:
• heat, for example, exhaust, air-conditioning systems, and
water pipes
• oils and corrosive liquids, for example, engine oil,
battery fluid, and brake fluid
Protect all the cables from sharp edges and mechanical
abrasions. Cables that pass through body panels or internal
bulkheads must be protected by rubber grommets. Holes in the
bulkhead need only be large enough to allow the end of the
cable with the smaller connector to pass through. Removing a
connector should be a last resort.
CAUTION Removal of factory-fitted connectors may cause
cable or connector faults.

Installing the antenna
14 Automatic Tuning Whip Antenna 9350 Installation Handbook
CAUTION
Crimp-style coaxial connectors are not suitable
for vehicle installations because they are
susceptible to mechanical damage and are not
weatherproof.
NOTE Any cabling under carpet or floor mats should
be clear of foot traffic.
