618C series synchronous FM radio transmitter
FM synchronous radio transmitter of 618C series is a high-tech synchronous broadcasting system with several FM broadcasting transmitter group network coverage in the broad geographical scope or one traffic route.The system adopts the same FM radio frequency,the same radio program,the same coverage field strength, which can realize the seamless reception without disruption in the field strength overlapping coverage area.It overcomes the drawbacks of small coverage caused by electromagnetic direct communication and curvature of earth,ease the electromagnetic pollution,increase the frequency utilization,expand and txtend the broadcasting service area.
Synchronous FM radio transmitter of 618C series consists of digital standard frequency,synchronous digital audio satellite receiver,FM synchronous radio actuator,power amplifier,and vertical polarization antenna,and other components.
