The 9350 Automatic Tuning Whip Antenna is designed to
provide continuous tuning for vehicle-mounted transceivers
that scan multiple frequencies. It is designed to withstand
extreme environmental and physical conditions. When tuning,
the antenna seeks the optimum tuning point, ensuring that the
best communications possible are achieved.
The 9350 Automatic Tuning Whip Antenna comprises:
•a 1.6 m (63 in) fibreglass primary whip, or a 1.65 m
(65 in) or 1.2 m (48 in) emergency stainless steel whip
•a spring
•an antenna tuner with connectors, base plate and earth
strap
You should unscrew the fibreglass or stainless steel whip from
the antenna base when the antenna is not in use.
When travelling in scrub or undergrowth, avoid overhanging
branches. Codan recommends that you carry the emergency
stainless steel whip with you in case the fibreglass whip is
damaged.
Connectors
There are two connectors at the base of the antenna as shown
in Figure 2.
qualified technician, to the relevant standards
and approvals.
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.
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

mounted on the side opposite to the driving
position.
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).
NOTE
You should consider any overall height
restrictions that are relevant to your vehicle.
The bracket should be located so that any flexing of the
antenna assembly does not damage the panels of the vehicle.
The shroud over the antenna tuner can flex up to
150 mm (6 in) without damage to the shroud.
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.
Conductive grease should be used on the
touching surfaces to help prevent corrosion.

Installing the antenna
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.
Installing an NVIS kit with a 9350 Automatic
Tuning Whip Antenna
An NVIS kit (Codan part number 15-00323) is available for
attaching to a 9350 antenna. For information on installing this
kit with the antenna see the instructions provided with the kit.
The NVIS kit is designed to improve the performance of short
to medium-range HF communications for the 9350 antenna by
increasing the high-angle radiation characteristics. Typically,
these communication distances are 20–500 km (12–310 mi).
The operating frequency range when using the NVIS kit is
1.6–12 MHz.
The vertical radiation pattern from a short vertical whip
antenna is very poor. As such, HF communications over short
distances may be difficult or non-existent from such an
antenna. The NVIS kit replaces the whip section of the 9350
antenna. The NVIS whip is longer and positioned horizontally
to improve the vertical radiation efficiency.
This section describes how to ensure the 9350 Automatic
Tuning Whip Antenna complies with the European
Electromagnetic Compatibility Directive 89/336/EEC and the
European Low Voltage Directive 73/23/EEC as called up in
the European Radio and Telecommunications Terminal
Equipment Directive 1999/5/EC.
This section also contains the requirements for FCC
compliance.
To ensure optimal transceiver performance and to avoid
exposure to excessive electromagnetic fields, the antenna
system must be installed according to the instructions
provided.
High voltages exist on the antenna during

transmission and tuning. Do not touch the
antenna during these activities. RF burns may
result.
Install the earthing system or counterpoise as
directed to prevent RF burns from any metal
part of the transceiver.
You should not transmit from your transceiver
or tune the antenna unless people are beyond the
safe working distance of 1.5 m (5 ft) of any part
of a 9350 Automatic Tuning Whip Antenna.
Safe working distance is based on continuous exposure to
CW-type transmissions, as set out in the ICNIRP Exposure
Guidelines (1998) for occupational exposure. Safe working
distance can be reduced with normal voice communication.
