KD-707BL HF Remote Control

Unit Price:$Stock:

        KD-707BL HF Remote Control is a remote connection unit in order to satisfy the special application for Barrett 2050 HF SSB transceiver . Practical Application :

         Human-computer interaction (handle, speaker, control panel)

         Partial separation between transmitters and antenna(middle or long distance)

         Solving the master control room and launch station are no longer in the same place , the distance between master control room and antenna erection point exceeds the max length of antenna feeder , ensure personnel safety in emergency .

  • Detailed introduction

Summary       

 

         The device connection is simple , extending functionality and system can be laid on their own or leased the optical fiber lines of  China Telecom (single mode fiber) to achieve remote connections between wireless short-wave radio control  and  transmitter antenna at the maximum 90KM area.

 

 

Function

 

      Keep the original way of HF radio operation,Compliance with operating habits

      Real time monitoring : devices in HF radio machine room

              Economize Investment cost :  follow the  original device of HF radio and HF transceiver

              Let  high power HF radio get away from interference (Computer, line telephone, electronic communication equipment)

              Shorten the feeder length between shortwave radio and antenna ,reduce radio frequency loss,improve the quality of communication.
