Advantages

*Ultra-Light & Mini Compact Structure, Fast Installation

Weighing merely 3.2kg, the R50 single frequency repeater is only 1/4 the volume of conventional repeaters, featuring ultra-portable and space-saving design. Equipped with exclusive wall-mounted accessories, it requires no fixed cabinet. Standard antenna ports are integrated with a built-in splitter without an external duplexer. The unit can be quickly deployed in tunnels, weak signal rooms and other scenarios with low installation cost and simple operation.

*Intelligent Temperature Control System, Ultra-High Operating Stability

Adopts intelligent temperature power regulation for steady long-term operation. The built-in cooling fan auto activates once the internal temperature hits 40°C. When temperature rises to 70°C, output power will be automatically reduced to cool down the device. This dual protection mechanism effectively extends service life and guarantees long-term reliable operation of the R50 repeater.

* Strong Transmission Performance & Longer Communication Range

Different from conventional and low-power mini repeaters, the R50 delivers stable 2W transmit output with zero TX power loss. Optimized overall receiver sensitivity greatly extends effective communication distance. Under single frequency repeater mode, terminals apply self-adaptive protocol to automatically identify relay signals or direct terminal signals for stable signal matching.

* Single Frequency Repeater Mode, Saves Frequency Resources

Supports dedicated single frequency relay mode. It realizes signal receiving and transmitting on one identical frequency channel, which drastically cuts frequency resource occupation. It lowers the difficulty of radio frequency license application and reduces annual frequency usage fees for enterprises. Besides single frequency repeater mode, the device also supports independent base station mode; a palm microphone is available as an optional accessory for base station deployment.

*High-Level Voice Encryption & Secure Authentication

Built-in AES256 & ARC4 encryption algorithms for signal transmission, plus exclusive ABELL proprietary encryption authentication protocol. The dual encryption system strengthens anti-interference capability and fully protects voice & data confidentiality during communication. It supports private individual calls and group calls for flexible team communication.

* Flexible Dual AC/DC Power Supply, Vehicle & Portable Deployment Supported

Integrated high-performance power module with universal 110V–240V AC input and auto AC/DC switching function. A 12V DC power interface is reserved for removable battery connection. It adapts to fixed wall installation, vehicle-mounted setup and mobile temporary deployment for diverse working scenarios.

*2.0” HD Full-View IPS Sunlight Readable Display

Comes with a 2.0-inch high-definition full-view IPS LCD screen, delivering delicate, clear visuals with outstanding sunlight visibility for outdoor daytime operation. Equipped with soft touch keypad for intuitive parameter configuration.

* Large Channel Storage Capacity, Multi-Zone Management

Adopts large-capacity memory chip, storing up to 1600 channels and supporting 100 independent zones. It meets channel classification demands of multi-department, multi-site enterprise teams.

*Simultaneous Audio & Data Transmission

Custom-developed digital concurrent transmission function for professional industrial users. The repeater transmits voice audio and digital data signals at the same time during communication, catering to data reporting, positioning and other integrated business needs.
