The RPSMA Female Crimp for LMR400 Cable is purpose‑built to give you a secure, low‑loss connection on one of the most popular large‑diameter RF cables: LMR‑400 and its equivalents. If you are running long antenna leads, outdoor feeds, or performance‑critical RF lines, the connector at each end matters just as much as the cable itself. This connector uses a reverse‑polarity SMA (RP‑SMA) female interface, which means it has the standard SMA external threads, but the center contact is reversed compared to a standard SMA. That makes it compatible with RP‑SMA male plugs commonly used on WiFi routers, access points, cellular gateways, and a wide range of RF modules. It is an excellent choice for custom cable builds, repairs, or upgrading pre‑made leads with higher quality terminations. Engineered for crimp installation, the body is designed to fit snugly over the prepared LMR‑400 cable, while a separate ferrule is crimped down onto the braid and outer jacket to create a solid mechanical and electrical connection. A plated metal housing provides corrosion resistance and physical strength, and the gold‑plated center contact ensures consistent, low‑resistance RF performance over time. The dielectric support inside the connector keeps the impedance stable, helping maintain low VSWR and minimal insertion loss in the system. Whether you are building a custom feed line for a rooftop antenna, extending a point‑to‑point wireless link, or assembling RF test leads, this RPSMA Female Crimp for LMR400 Cable gives you the flexibility of field‑terminating heavy‑duty coax without sacrificing performance. With the proper coax stripper and crimp tool sized for LMR‑400, installation is straightforward and repeatable, making it suitable for both professional installers and experienced hobbyists.
