Professional Repeater Module

BF-TR925

BF-TR925 vehicular or manpack repeater provides on-site communication and remotely connects via IP or satellite. It work as a repeater as well as a dispatcher with BelFone communication systems. With features of fast deployment, flexible networking, IP68 water & dust proof and military standard ruggedness, it usually works with BF-TR900 fixed repeater, when coverage is needed at a special event or incident to swiftly provide local DMR or analog on-site portable radio connection. It delivers high performance, high reliability two-way radio service and is the best choice for harsh outdoor conditions.
