The SMA Male Clamp for LMR400 Cable is a purpose-built RF connector designed to give you a clean, secure, and low-loss termination on one of the most popular coax cable sizes used today. Precision-engineered to fit LMR400 and equivalent 400‑series coax, it delivers a stable impedance match and dependable performance from installation day onward. Instead of relying on a loose or improvised fit, this connector uses a firm clamp-style attachment that grips the cable jacket and shield evenly. That means less chance of intermittent connections, reduced risk of pull-out, and more consistent electrical contact across a wide range of applications. Whether you’re assembling custom feed lines for antennas, linking RF modules, or extending runs to test gear, this SMA male clamp provides a solid mechanical and electrical interface. The connector’s SMA male interface mates with standard SMA female jacks commonly found on RF modules, routers, radios, antenna mounts, and measurement devices. Its compact form factor makes it well suited to tight enclosures or crowded panels, while the knurled coupling nut allows for secure hand-tight or torque-wrench installation. Designed with RF performance in mind, the internal contact geometry is optimized to maintain low VSWR and minimal insertion loss when properly terminated. The durable metal body resists wear from repeated mating cycles and offers good shielding against external interference, helping to keep your signal clean and consistent. Whether you are a professional installer or an RF enthusiast, this SMA Male Clamp for LMR400 Cable helps you build reliable coax assemblies that look professional and perform to expectation. With the right tools and a careful installation, you can count on this connector for long-term, stable connectivity in both indoor and outdoor projects.
