Setting up a compact, durable and reliable infrastructure is a key task for air traffic control (ATC) authorities. The R&S®KG4200 ATC SYSTEM RACK ATC System Rack ATC system rack allows them to quickly plan such an infrastructure and put it into operation.


The R&S®KG4200 ATC SYSTEM RACK ATC System Rack system rack is the basis for a fully equipped radio system consisting of R&S®SERIES4200 Software Defined Radios radios. Even systems with a large number of radio channels can be implemented in a minimum of space. Thanks to the standardized setup, various commercial-ofthe- shelf (COTS) equipment can be integrated alongside the radios. The radio equipment and options can easily be installed, retrofitted and removed.


The R&S®KG4200 ATC SYSTEM RACK ATC System Rack rack is made of stainless steel and aluminum, which ensures long life and high durability. It protects the equipment against mechanical stress and unauthorized access to the integrated components.


Key Facts


Specially developed for ATC systems, for integration of R&S®SERIES4200 Software Defined Radios radios, R&S®GV4000 Multi-Link Controller multilink controller and filters

Up to 24 transmitters/transceivers or up to 48 receivers

Up to eight transceiver channels (MAIN/STANDBY) with filters in one rack

Wide variety of standardized options

Radios, COTS and third-party equipment in one rack


Features & Benefits


Compact, scalable setup

The R&S®KG4200 provides 46 height units (HU), which means it can accommodate a maximum of equipment in a minimum of space. It can hold up to 24 transmitters/ transceivers or 48 receivers. The R&S®KG4200 is offered in different models for different numbers of radios. As a result, it can be used in small tower systems as well as in large-scale radio stations.


Easy to install

Preinstalled rackmounts and KRONE® interfaces make it easy for the user to install radios and COTS products in the rack. The AC power supply is prewired and ready to be connected, minimizing setup time.


Flexible system integration

Thanks to the diverse R&S®KG4200 options, many different system versions can be implemented, e.g. MAIN/STANDBY installation, backup DC power supply or integration of n+m redundancy when using the R&S®GV4000 multilink controller. This allows, for example, a configuration with eight filtered radio channels based on R&S®Series4200 transmitters or transceivers in MAIN/ STANDBY operation in one rack.


Installation of additional third-party equipment

The 19" rack design makes it possible to install additional COTS and other third-party equipment such as Ethernet switches for network-based remote monitoring and control systems or VoIP applications.


No additional cooling required

The perforated rear panel and door make sure that a completely equipped R&S®KG4200 is sufficiently cooled at a room temperature of up to +30 °C. The rack design is tailored to the cooling concept of the R&S®Series4200 radios so that several racks can be set up next to each other. No modifications are required.


Durable and secure

The R&S®KG4200 consists of a stainless steel frame and aluminum side and rear panels that protect the integrated components from mechanical stress. Lockable doors are available to prevent unauthorized access to the radios.


Uniform appearance

The color of the R&S®KG4200 rack is matched to the design of the R&S®Series4200 radios.
