DMR Single Frequency Repeater

BF-SFR600

BF-SFR600 is our new single frequency repeater solution, which is also able to function as a base station within a system. As a single frequency repeater, BF-SFR600 allocates one timeslot to receive signals and the other to transmit at the same frequency, using DMO mode to extend radio coverage. This repeater supports both AC and DC power inputs. When DC power supply is unplugged, the device automatically turns to an AC power source. The two auto-switchable power sources serve as each other’s backup, thus delivering more flexibility and stability. This is a smart and cost-effective choice for commercial users who need extra coverage.

DMR Mobile/Repeater Dual Modes
DMR Mobile/Repeater Dual Modes
BF-SFR600 can be used both as an ordinary mobile radio and a single frequency repeater; it brings more flexibility and efficiency to your business.
Auto-switch Power Design
Auto-switch Power Design
High and low power switchable: choose high (30W) and low (10W) power output according to the occasion, avoiding unnecessary energy consumption.
Analog/Digital Back-to-Back Interconnect(optional)
Analog/Digital Back-to-Back Interconnect(optional)
It supports different operating modes of analog and digital to interconnect for voice calls, allowing analog users to communication with digital users and vice versa.


High/Low Power Switchable

You can choose between high (25W) and low(10W) power output according to the occasion. This can effectively avoid unnecessary energy consumption.


Good Heat Dispersion

The high-quality built-in fan provides sufficient airflow for operation within the specified temperature without derating, and thus enables BF-SFR600 to operate stably for long hours.


Multiple Sites via IP(Factory Option)

BF-SFR600 supports network connection via the IP port to form a private radio network, thus meeting data and voice communication needs for wide-area coverage and dispersed locations.


Repeater Power Backup(Optional)

With DC/AC dual power sources, the device automatically turns to an AC power source when the DC power supply is unplugged. The two auto-switchable power sources serve as each other's backup, thus delivering more flexibility and stability.


Analog/Digital Back-to-Back Interconnect(Optional)

BF-SFR600 supports different operating modes of analog and digital to interconnect for voice crosspatch, allowing analog users to communicate with digital users and vice versa. This delivers a smooth transition from analog to digital.
