Danphone NAVTEX Transmitter Systems

With more than 40 NAVTEX transmitters delivered since 2007, Danphone is truly a leading supplier of NAVTEX systems worldwide.

The IP-based Danphone NAVTEX transmitter system is scalable and can be customised to suit all requirements - from a single-transmitter setup to a complex national system with multiple operators and transmitter sites installed at various remote locations.

Incorporating Danphone’s intuitive graphical user interface, the system offers a wide range of opportunities, such as PC remote control and the facility of editing and compiling NAVTEX messages to be transmitted automatically at pre-selected times and frequencies.

The server free architecture ensures transmission of prepared messages even if the network is down.

The transmitters are designed for standard 19" rack mount and can be installed in separate cabinets or stacked together in one cabinet. For example, a 1,800 mm / 40 HU cabinet can contain all the equipment needed for a main/standby system with duplicated transmitters and power supplies.
