Belden 3079ALS Coaxial Cable Overview

The Belden 3079ALS is a versatile, high-performance coaxial cable specifically designed for use in the transmission of low-loss signals in various applications, including RF (Radio Frequency), broadband, and telecommunications systems. This cable is particularly well-suited for environments where minimizing signal degradation over long distances is critical.

Key Features:

• Construction: The 3079ALS features a solid copper conductor, which ensures excellent electrical conductivity and signal integrity. The cable is designed with an aluminum foil and braid shield, providing robust protection against electromagnetic interference (EMI) and radio frequency interference (RFI).
• Insulation: The cable includes a polyethylene (PE) dielectric, which is chosen for its low signal loss and consistent impedance characteristics, critical for maintaining the quality of high-frequency signals.
• Outer Jacket: The cable is encased in a PVC outer jacket that offers durability and protection against environmental factors, making it suitable for both indoor and outdoor installations.
• Applications: The 3079ALS is ideal for a variety of applications, including antenna systems, CATV, CCTV, and other communication systems that require reliable signal transmission with minimal loss.

Electrical Performance:

• Impedance: 75 ohms, which is the standard impedance for many RF applications.
• Capacitance: The cable has a capacitance of approximately 67 pF/m, which is optimized for low-loss signal transmission.
• Frequency Range: It supports a wide frequency range, making it versatile for various communication needs.
