Belfone BF-SFR600 Single Frequency Repeater

BF-SFR600 is our new single frequency repeater solution, which is also able to function as a base station within a system.


  • latest terminal that can be use either as Base Station or Single Frequency Repeater.

  • helps you to extend your radio communication coverage by enabling 2 time slot features to serves as a single frequency DMO repeater.

  • supports both AC and DC power inputs with an auto-switchable power sources between both power input.


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.
