FEATURES AT A GLANCE
Rugged, best-in-class
mobile antenna
Fast, optimum tuning
High radiation efficiency
Continuous tuning
Two whips supplied
Sensitive to weak signals
The 9350M Automatic Tuning Whip Antenna is designed for
maximum durability and reliability in demanding mobile
military operations. It is used with transceivers
that have a large channel capacity.
RUGGED DESIGN
The 9350M Antenna is constructed to withstand the harsh fi eld
and environmental conditions common in military operations.
It meets or exceeds the shock and vibrations requirement for MIL-STD-810.
The main antenna section is constructed of fi breglass reinforced nylon.
This provides a weatherproof housing for the control and tuning devices,
which are fi tted inside. It is mounted on an anti-vibration base that
incorporates rubber mounts.
The 9350M Antenna will operate in a broad range of temperatures.
FAST, OPTIMUM TUNING
Typically, the 9350M takes only a few seconds to tune to any frequency.
It will seek the optimum tuning point for all operating conditions —
this ensures the best communications possible.
HIGH RADIATION EFFICIENCY
The 9350M Antenna has a comparably high rate of radiation effi ciency.
It is rated for maximum voice power of 125 watts PEP.
CONTINUOUS TUNING
The whip antenna uses a microprocessor controlled stepper motor to
provide continuous tuning to any required frequency over the transmit /
receive operating range of 2 to 30 MHz.
TWO WHIPS SUPPLIED
Two whip top sections are provided with the 9350M Antenna. The
standard or primary whip is a wire that is encased in a polyurethane
covered fi breglass rod. It is designed to withstand substantial fl exing and
hard knocks and operates over the full frequency range of this antenna.
The shorter, secondary whip is manufactured from stainless steel.
It is designed for use as a backup in emergency situations when the
standard whip has been damaged. This whip is only suitable for operation
over a transmit frequency range of 2.5 to 30 MHz and is less effi cient than
the primary whip.
SENSITIVE TO WEAK SIGNALS
When in Scan or Free Tune Receiver mode, a broadband amplifi er is
activated. This makes the antenna sensitive to even the weakest signals
over the entire frequency range.

NEAR VERTICAL INCIDENCE SKYWAVE (NVIS) KIT
The NVIS kit is an add-on accessory for the CODAN™
9350M Antenna.
Short vertical whip antennas are poor radiators
at high take-off angles. This makes short distance
communications diffi cult, especially so in hilly terrain.
Making the whip longer and more horizontal improves
the high take-off angle radiation effi ciency.
Improves short-range communications
Transmit and receive paths over the range of 0 to 500 kms
will be greatly improved with the addition of the NVIS kit.
Easily attached to a variety of vehicles
The NVIS kit can be quickly and easily attached to a wide
variety of vehicles. All fi tting instructions are provided —
no special tools are required.
Rugged design
The tough design of the NVIS has been proven through
extensive fi eld testing.
Easy to transport
The NVIS kit is supplied in a canvas bag for ease
of transportation.
Note: The frequency range of the NVIS kit is
1.6 to 12 MHz.
