  • INQUIRY

      Because the 75Ohm telecom cable 78 rf feeder cable  is hard, they are all used outdoors, for connecting 7/8 feeders and equipment for switching. coaxial cable main task is to effectively transmit signal energy, transmit the signal power from the transmitter to the input of the transmitting antenna with minimal loss, or transmit the signal received by the antenna to the receiver input with minimal loss, while itself No spurious interference signals are generated, so the transmission line must be shielded.
