STR-600 25W Radio Repeater
STR-600 Mini Radio Repeater
Product Introduction:
The 25W signal amplifier(radio repeater) STR-600 is designed with outstanding features of compact, heavy-duty,robust, reliable, durable, easy installtion and easy operation.
Users who want to enlarge the limited coverage of handheld analog two-way radios or to strengthen the communication signals in some communication “dead areas” such as underground floors, stairs etc. can adopt this equipment. Users can input power supply directly from cars(13.8V DC) or from AC main power 90-260V.
