Marine Two Way VHF Radio Telephone
Marine Two Way VHF Radio Telephone
This marine VFH radio telephone is the VHF voice terminal equipment of a ship, mainly used for short-range communication at sea, such as the communication of bridge-to-bridge and bridge-to- rescue site; and it use VHF band when communicating.
Features:
1. Carefully designing circuit and process, using aluminum alloy shell, superior anti-jamming capability
2. 100% waterproof and good heat dissipation enabling the radio telephone to work in rugged environment
3. Dual-band and tri-band unattended function
4. Single key converting to international communication channel 16 or channel 9
5. 88 dedicated channels
6. All the American, international and Canada channels, 10 weather channels
7. Prior quick scanning
8. CCS approved
