A 1/2″ feeder cable refers to a type of coaxial cable commonly used in telecommunications and RF (radio frequency) applications. The “1/2″ measurement refers to the outer diameter of the cable, which is approximately 0.5 inches or 12.7 millimeters.
Feeder cables are used to transmit RF signals, typically for applications such as broadcasting, cellular communication, satellite communication, and other wireless systems. The coaxial design of the cable provides shielding to minimize signal interference and loss.
The 1/2″ feeder cable is often preferred for medium to high-power applications due to its larger diameter, which allows for better signal transmission with lower signal loss over longer distances compared to smaller diameter cables. It typically has a relatively low loss characteristic and can handle higher power levels.
Different variations of 1/2” feeder cables may exist, such as 50-ohm or 75-ohm versions, with varying impedance values depending on the specific application requirements. The choice of feeder cable depends on factors such as the frequency range, power requirements, and environmental conditions of the intended application.
