Antenne Mobile 9350 (212 kb) 
The CODAN 9350 Automatic Tuning Whip HF Antenna is designed for mobile operation with CODAN transceivers that have a large channel capacity.
Key features
Rugged design
The CODAN 9350 antenna is constructed to withstand the severe environmental conditions usually experienced in some of the more remote areas of the world. It meets or exceeds the shock and vibrations requirements for MIL-STD-810.
The main antenna section is constructed of fiberglass reinforced nylon. This provides a weatherproof housing for the control and tuning devices, which are fitted inside. It is mounted on an anti-vibration base that incorporates rubber mounts. These are likely to be met while travelling on unsealed roads or tracks.
The CODAN 9350 antenna will operate in a broad range of temperatures.
Fast, optimum tuning
Typically, the CODAN 9350 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 CODAN 9350 antenna has a comparably high rate of radiation efficiency. It is rated for maximum voice power of 125 watts PEP.
Additional features
Continuous tuning
The CODAN whip antenna uses a microprocessor controlled stepper motor to provide continuous tuning to any required frequency over the transmit/receive operating range of 2–30MHz.
Two whips supplied
Two whip top sections are provided with the CODAN 9350 antenna. The standard or primary whip is a wire that is encased in a polyurethane covered fibreglass rod. It is designed to withstand substantial flexing 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 2.5–30MHz and is less efficient than the primary whip.
Sensitive to weak signals
When in Scan or Free Tune Receiver mode, a broadband amplifier is activated. This makes the antenna sensitive to even the weakest signals over the entire frequency range.

The Near Vertical Incidence Skywave (NVIS) kit is an add-on accessory for the Codan 9350 HF antenna
Short vertical whip antennas are poor radiators at high take-off angles. This makes short distance communications difficult, especially so in hilly terrain. Making the whip longer and more horizontal improves the high take-off angle radiation efficiency.
Key features
Improves short-range communications
Transmit and receive paths over the range of 0–500 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 fitting instructions are provided—no special tools are required.
Additional features
Rugged design
The tough design of the NVIS has been proven through extensive field testing.
Easy to transport
The NVIS kit is supplied in a canvas bag for ease of transportation.
