TETRA Remote Control Head (1)

About the product

The RH150-13 TETRA Remote Control Head is a Control and Display Unit (CDU) that is designed to provide a remote second facility to the main CDU (CH150-14 or CH250-13) for controlling a Chelton airborne TETRA radio sub-system. The unit can be mounted in a console or otherwise away from the main CDU. The maximum wiring loom length between the main and remote CDUs must not exceed 10 metres.

  • DZUS Mounting
  • NVIS Compatible
  • Large Display Screen with Automatic Dimming
  • Keypad Suitable for the Gloved User

Main functions of the RH150-13 TETRA Remote Control Head

  • Repeats the digital video of the main CDU
  • Monitors the front panel keyboard for key presses
  • Communicates key presses to the main CDU
  • Provides automatic display brightness adjustment independently of the main CDU

The design of the MMI, display and controls benefits from Chelton's extensive experience of fielding TETRA radios for airborne use, which, because of the unique nature of TETRA networks, is significantly more challenging than operating standard tactical radios.
