The SMA Male Crimp for LMR400 Cable is engineered for installers who demand stable, low-loss RF performance in a compact, rugged form factor. Designed for use with LMR-400 and other 400‑series 50 Ohm coaxial cables, this connector combines a threaded SMA interface with a crimp/solder termination method to deliver both electrical integrity and long-term mechanical reliability. At the front end, the standard SMA male interface uses a precision threaded coupling that resists loosening from vibration and handling, making it a solid choice for field gear, mobile installations, and high‑duty RF systems. When mated with a quality SMA female jack, it helps maintain consistent impedance and minimizes reflections, supporting clean signal transfer from DC through typical LMR‑400 operating bands. On the cable side, the connector is built around a crimp ferrule and soldered center pin. The center conductor is soldered to the pin for a secure, low-resistance joint, while the outer ferrule is crimped over the braid and jacket to provide strain relief and a solid 360° shield connection. When installed with the correct stripping dimensions and crimp die, the result is a termination that stands up to repeated connects/disconnects and everyday mechanical stress. This SMA male crimp is a practical choice for custom cable assemblies in RF labs, ham radio stations, wireless ISP infrastructure, and general-purpose test leads. Whether you are replacing a worn connector or building a new run of LMR‑400, it offers a straightforward, repeatable installation process using standard coax prep tools, a soldering iron, and an appropriate crimp tool. Housed in a durable metal body with a plated finish, this connector is designed to provide years of dependable service when properly installed and protected from environmental extremes.
