Product Details of RF 3/8'' flexible feeder Cable

RF 3/8" flexible feeder cable is ized coaxial cable widely used in telecommunications,broadcasting and high-frequency signal transmission.

Features

1. Inner Conductor: Solid copper clad aluminum of diameter 3.10mm. This combines aluminum's lightweight properties with copper's conductivity,optimizing cost and performance.
2. Outer Conductor:Corrugated cooper tube provides flexibility,mechanical strength and enhanced shielding against electromagnetic interference.
3. Insulation: Foamed polyethylene layer reducing dielectric losses and improving signal propagation speed
4. Outer Sheath: PE or low smoke zero halogen(LSZH) material offers flame retardance and minimal toxic emissions in confined spaces.
5. Packing: RF 3/8" flexible feeder cable is often packed in carton and wooden drum.

Advantage

1.Low Attenuation: Engineered for minimal signal loss across frequencies. Enable longer transmission distances without repeaters, critical for tower-to-antenna links.
2.High shielding Effectiveness: The annular corrugated copper outer conductor provides＞90% EMI shielding, reducing noise and cross-talk
3.Weather Resistance: LSZH sheath withstands UV exposure, moisture and extreme temperature (-45℃ to +85℃)
4.Mechanical Flexibility: Corrugated design allows bending without compromising shielding. RF 3/8" flexible feeder cable is ideal for installations in tight spaces.
In the conclusion,the RF 3/8" flexible feeder cable excels in low loss signal transmission,environmental durability and installation versatility, making it ideal for modern RF infrastructure. Its balanced design optimizes performance for high-frequency applications while minimizing life cycle costs.
