Feeder Cable: Signal Transmission Cable in Communication Systems
Feeder cable is used to transmit signals from signal sources to loads. In communication systems, it’s often used to connect transmitters or receivers to antennas, transmitting RF signals for antenna emission or receiving signals from antennas and transmitting them to receivers.
RF coaxial feeders serve the purpose of powering the RF components which include antennas, transmitters, and receivers. To facilitate efficient signal transfer, these coaxial feeders feature low impedance matching. Power, distance, and frequency needs determine the appropriate category of coaxial feeders that will be used.

What is the function of a feeder cable?
In communication systems, a feeder cable transmits signals from signal sources to loads. It connects transmitters or receivers to antennas, enabling RF signal emission and reception.
Are feeder cables different from regular cables?
Yes. Feeder cables are specifically designed for RF signal transmission. They have better shielding and low - loss properties compared to regular cables to ensure efficient RF signal transfer.
How long can feeder cables be used for signal transmission?
The length depends on the type of feeder cable and the application. Generally, high - quality feeder cables can transmit signals over long distances with acceptable signal attenuation.
