Codan Military HF Transceiver NGT MR

Codan Military HF Transceiver NGT MR
RUGGED DESIGN
The NGT™ MR meets or exceeds environmental specifi cations for shock, vibration and blowing dust. In addition to MIL-STD-810F, the RF unit is IP52 rated and the handset is IP41 rated. It also provides complete protection against reverse polarity, over voltage, antenna mismatch and temperature.

VOICE ENCRYPTION
Voice security is provided through an optional voice encryption
module, which is fi tted inside the NGT™ MR. The encryption is based on a 128-bit digital algorithm to meet the unique demands of HF propagation. Up to 98 eight-bit user programmable key codes are available to enable 10E10000 key code combinations. These keys are never transmitted on-air and as a result cannot be intercepted. To start Secure Mode users simply press the SEC button on the handset. The NGT™ MR offers an additional level of security once a secure voice link is in session via a predefi ned 4 digit PIN. The two or more parties involved in communication enter the known 4 digit PIN at any time to create a separate secure session. Also, users do not have to synchronize at the beginning or during a secure session. This eliminates delays and means that there is no limit to the number of participants. Management and programming of keys is simple through Windows® terminal-based software.
 
 
INNOVATIVE USER INTERFACE
Codan’s cleverly designed NGT™ MR Handset and intuitive interface provides many benefi ts over traditional removable front panel designs. Its small size and light weight make it simple to install in many locations, especially in vehicles where space is limited. The menu system includes a call address list and the keypad is arranged like a mobile phone to ensure that radio operation is simple, familiar and intuitive. With convenient access to the RS232 port, located on the base of the Handset, users will fi nd it quick and easy to program the RF unit.
