Kerberos Radio-In-A-Box (RIAB)
Tactical FM Broadcast System
87.5–108.0 MHz
A deployable FM broadcast system engineered for tactical field operations.
The Kerberos Radio-In-A-Box (RIAB) gives field teams a complete, ruggedized, mission-ready portable FM radio station: transmitter, audio, automation, power, networking, cabling, antenna package, documentation, and Kerberos support. Purpose-built as a field radio broadcast system for military, emergency response, and humanitarian operations.
Unlike many low-cost broadcast kits and imported radio packages, Kerberos RIAB is built around primary components sourced from the United States or close U.S. partner countries, including the United Kingdom, Italy, Germany, France, and Canada. Kerberos uses this supply-chain approach because reliability matters in the field: over 16 years, more than 700 Kerberos broadcast systems have been fielded with zero field failures to date and no warranty returns.
Sixteen years building tactical broadcast systems for real field environments.
YES - we are the LARGEST supplier of RIABs in the world - but we don't like to brag. Much. The Kerberos Radio-In-A-Box (RIAB) did not start as a hobby transmitter that was later ruggedized which many of our competitors did. Wrapping a toy in a fancy box still makes it a toy. The Kerberos RIAB was built from the field backward: around the requirements, limitations, and operating conditions described by real users working in remote, austere, and high-pressure environments.
Kerberos listened to the operators, partner forces, government teams, and field personnel who needed reliable FM broadcast capability without requiring a radio engineer at every site. The result was a system designed around practical deployment: fast setup, simple connections, reliable broadcast, remote control, repeatable procedures, operator training, and supportable hardware.
Kerberos also made a deliberate supply-chain decision. Kerberos RIAB is built around primary components sourced from the United States or close U.S. partner countries, including the United Kingdom, Italy, Germany, France, and Canada. Transmitters, amplifiers, cabling, antennas, cases, and other critical system elements are selected for reliability, supportability, and long-term field performance — not simply lowest cost. And finally - we brought on a dedicated team of Broadcast Engineers, professional real-world DJ's, Power Engineers, RF Engineers, and mechanical engineers to ensure that we continue to have ZERO (0) operational issues in the field - wherever that field be.
The result is a professional FM radio station packaged for tactical, humanitarian, emergency-response, and civil-military operations — one of the most widely fielded tactical FM broadcast systems of its kind, with more than 700 systems fielded, zero field failures to date, and no warranty returns.
Built so non-radio operators can get on the air.
The Kerberos International Radio-In-A-Box (RIAB) is a full professional FM radio station packaged for field deployment. Kerberos RIAB systems are used in more than 26 countries for live programming, news, sports, weather, public information, music, emergency messaging, and day-to-day broadcast operations. Our systems are currently in planes, helicopters, aerostats, 12/24VDC vehicle systems and hard-wired into brick&mortar buildings.
Kerberos RIAB includes the broadcast software, automation tools, audio capability, programming control, and operator workflow needed to run a professional FM station. A trained broadcaster or DJ can operate it like a conventional radio station, while a local operator with little or no radio experience can still bring the system on air quickly by following the quick setup procedure chart.
The system supports live local operation, pre-programmed playlists, recorded messages, remote programming, and remote operator control. A local DJ can run the station in person, then hand off to automated programming or a remote operator when needed. Content can be prepared days or weeks in advance and modified on the fly as the mission, audience, or operating environment changes.
Kerberos RIAB was built to cover the full operating range: professional broadcasters who want full station capability, and field teams that simply need to broadcast reliable information fast. Based on Kerberos field experience, approximately 98% of trained operators are able to get on the air within the first hour when following the quick setup procedure.
Choose the site
Select the broadcast location based on coverage requirement, terrain, power availability, antenna plan, and mission need.
Raise the antenna
Deploy the mast or antenna package according to the site plan and coverage requirement.
Connect four cables
Connect the primary audio, RF, power, and network/control connections as configured.
Go on air
Load programming, verify output, and begin local broadcast operation.
Set it, automate it, and control it from anywhere.
Optional reachback capability allows Kerberos RIAB to be placed into automatic operation and controlled remotely. Operators can build playlists and messaging days or weeks ahead of time, then modify content on the fly as the mission changes.
Multiple Kerberos RIAB stations can be coordinated and controlled at the same time across cellular, SATCOM, hardwired LAN/RJ45, or customer-provided network infrastructure.
SATCOM
Reachback over satellite networks where conventional infrastructure is unavailable.
LAN / RJ45
Hardwired network connection for fixed sites, command nodes, and supported facilities.
Cellular
Cellular connection option where coverage and customer network policy allow it.
Multi-Station
Coordinate multiple broadcast stations from a central control concept.
Every system is built for repeatable deployment, not one-off demonstration.
After assembly, Kerberos RIAB systems undergo a full week of intensive testing to verify operation, configuration, cabling, audio chain, transmitter control, automation, labeling, packaging, and field readiness.
Engineered Integration
Audio, broadcast, power, network, and control systems are integrated into a rugged package before the customer receives it.
One-Week Test Cycle
Systems are tested before release to confirm that the package operates as a complete radio station, not merely as separate components.
Deployment Packaging
Ruggedized transport cases, labeling, secure drawers, cable storage, and support documentation are part of the system design.
