The AR20 automatic rebroadcast station is a device allowing automatic rebroadcasting in fixed frequency operation modes of transceivers complying with the requirements of the STANAG 4204 standard and of transceivers communicating in frequency hopping modes using HW20 modulation, i.e. RF23, RF20, RF2050.

• Automatic rebroadcasting of services in simplex or semi-duplex frequency hopping channel, such as transmission of short text messages, ALERT, authentication, and notification of interruption BREAK IN.
• Automatic rebroadcasting of P2P data communication or according to MIL-STD-188-220 (NET) in simplex or semi-duplex frequency hopping channel.
• Automatic synchronization of all terminal transceivers from the AR20.
• Automatic rebroadcasting of voice communication in simplex or semi-duplex fixed frequency channel or frequency hopping channel.
• Automatic rebroadcasting of data communication in simplex or semi-duplex fixed frequency channel according to MIL-STD-188-220 (NET).
• Automatic rebroadcasting of voice communication in simplex or semi-duplex fixed frequency channel with encryption unit enabled.
• Automatic rebroadcasting of short encrypted FLASH messages in simplex or semi-duplex fixed frequency channel.
• Rapid transition to radio communication between AR20 and terminal transceivers without rebroadcasting to another network.
• Connection to a third radio station, which is a terminal transceiver of another rebroadcast station, while ensuring compatibility of all types of communication in fixed frequency or frequency hopping channels.
