The RG400 Coaxial Cable is a rugged, high-quality RF coaxial cable engineered for applications where reliability and signal integrity are non‑negotiable. With a characteristic impedance of 50 ohms and low attenuation over a wide frequency range, it has become a go‑to choice for avionics, RF communications, and precision test setups. At its core, the cable is built to handle demanding environments. The inner conductor and dielectric are matched to maintain consistent impedance and stable electrical performance, helping to minimize reflections and losses along the line. A double-shielded construction—typically using braided metal shields—provides strong protection against electromagnetic interference and crosstalk, so your signal remains clean even in crowded RF environments. The outer jacket is designed to withstand elevated temperatures and general mechanical stress, making RG400 suitable for use in aircraft, defense systems, industrial equipment, and other harsh installations where lesser cables may degrade prematurely. Despite its robustness, the cable remains flexible enough to route through tight spaces, cable harnesses, and equipment racks without excessive stiffness. In real-world use, RG400 is frequently selected for antenna feedlines, RF jumpers between radios and auxiliary equipment, and interconnects in lab and field test gear. Its combination of low loss, strong shielding, and mechanical durability helps maintain consistent performance over time, reducing the need for frequent replacements or troubleshooting due to cable-related issues. Whether you are outfitting new RF hardware, upgrading older cabling, or building custom assemblies, RG400 Coaxial Cable offers a reliable blend of electrical performance and physical resilience. It’s well-suited for anyone who needs professional-grade RF transmission with the confidence that the cable will hold up under continuous use and demanding conditions.
