The RG393 Coaxial Cable is designed for users who need reliable, repeatable RF performance in environments where ordinary cable simply will not hold up. With a characteristic impedance of 50 ohms and a robust, low‑loss construction, it delivers clean transmission for RF and microwave systems across a wide operating band. At the core of the cable is a high‑quality, silver‑plated copper or silver‑plated copper‑clad steel conductor (depending on specific build), chosen for its excellent conductivity and stable performance at high frequencies. This inner conductor is surrounded by a precision dielectric that maintains consistent impedance and minimizes signal reflections, helping to keep VSWR low across your operating range. To protect the signal from external interference, RG393 uses a double‑shielded design with overlapping silver‑plated copper braids. This high level of shielding offers strong protection against EMI and RFI, which is critical in dense test benches, communication racks, and mission‑critical systems where multiple RF sources operate side by side. On the outside, a durable, high‑temperature‑rated jacket provides mechanical strength and resistance to abrasion, chemicals, and challenging environmental conditions. This makes RG393 suitable for both indoor and outdoor runs, high‑power feedlines, and demanding mobile or industrial applications where cables are frequently moved, flexed, or routed through tight spaces. Whether you are upgrading a test setup, building custom RF assemblies, or running high‑power links to antennas, the RG393 Coaxial Cable offers a dependable balance of power handling, attenuation performance, and rugged durability, making it a trusted choice for engineers, installers, and RF technicians alike.
