Analoge Funkmodule

The ARM 26 is an analogue radio module for the Cab Radio MESA 26. It allows the operational communication in analogue radio systems in the frequency bands:

  • 70 cm (according to UIC 751-3) and
  • 2 m

The unit is modular and thus the respective customer requirements configurable. It consists of three functional units:

  • Power supply for the connection of the on-board voltage and the generation of the device’s internal operating voltage
  • 2 m radio module
  • 70 m radio module

The analog radio is available for different voltage variants and the following specifications:

  • ARM 26-xxx/2 for use in 2 m band
  • ARM 26-xxx/7 for use in 70 cm band
  • ARM 26-xxx/2/7 for use in both frequency bands

(xxx = Voltage input 24 V, 36 V, 48 V, 72 V or 110 V)
