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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for **LMR‑400 and equivalent 0.405\" OD coaxial cable**\u003c\/li\u003e\n\u003cli\u003eensuring a precise mechanical fit and secure termination.\u003c\/li\u003e\n\u003cli\u003e**RP‑SMA female interface** with standard SMA external threads and reverse‑polarity center contact for compatibility with RP‑SMA male devices used in WiFi and wireless gear.\u003c\/li\u003e\n\u003cli\u003e**Crimp‑style attachment** with separate ferrule for strong mechanical retention and reliable electrical contact to the cable braid.\u003c\/li\u003e\n\u003cli\u003e**50 Ohm impedance**\u003c\/li\u003e\n\u003cli\u003esuitable for most RF\u003c\/li\u003e\n\u003cli\u003eWiFi\u003c\/li\u003e\n\u003cli\u003eand cellular applications requiring matched transmission lines.\u003c\/li\u003e\n\u003cli\u003eDurable **metal body plating** (typically nickel) for corrosion resistance and long‑term outdoor or indoor use.\u003c\/li\u003e\n\u003cli\u003e**Gold‑plated center contact** to maintain low contact resistance and excellent RF conductivity.\u003c\/li\u003e\n\u003cli\u003eCompatible with **LMR‑400\u003c\/li\u003e\n\u003cli\u003eRG‑8\u003c\/li\u003e\n\u003cli\u003eRG‑213 and similar large‑diameter coaxial cables**\u003c\/li\u003e\n\u003cli\u003eoffering flexibility across multiple cable types.\u003c\/li\u003e\n\u003cli\u003eIdeal for **custom RF cable assemblies\u003c\/li\u003e\n\u003cli\u003eantenna feed lines\u003c\/li\u003e\n\u003cli\u003eWiFi\u003c\/li\u003e\n\u003cli\u003eLTE\u003c\/li\u003e\n\u003cli\u003eand point‑to‑point wireless links** where low loss and reliability are critical.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dipeshwari","offers":[{"title":"Default Title","offer_id":45282232434742,"sku":"DERPSMA25035","price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0620\/6075\/7046\/files\/DERPSMA25035_1.jpg?v=1778230930","url":"https:\/\/dipeshwari.in\/products\/rpsma-female-crimp-for-lmr400-cable","provider":"Dipeshwari Engineering Work ","version":"1.0","type":"link"}
