The SMA Female Straight Connector for LMR400 Cable is built for installers and RF enthusiasts who demand dependable performance from every termination. Designed specifically to fit LMR-400 and equivalent large-diameter 50-ohm coaxial cables, it provides a precise and stable interface for a wide range of RF and microwave applications. Featuring the familiar threaded SMA coupling, this straight female connector ensures a tight, vibration-resistant connection that won’t loosen over time like push-on styles often do. The precision-machined body and carefully controlled dimensions help minimize return loss and maintain consistent impedance, supporting cleaner signals and reduced insertion loss across the cable run. This connector is ideal for custom antenna leads, radio jumpers, GPS and RFID setups, test bench cables, wireless infrastructure, and general RF projects where LMR-400 is used for its low-loss characteristics. When properly terminated with the correct tools, it delivers a professional, rugged finish that stands up well to everyday use. The design typically includes a crimp ferrule or clamp interface for the outer braid and a secure attachment method for the center conductor, ensuring good electrical contact and robust mechanical strength. Because it is a standard SMA female interface, it mates directly with SMA male plugs on radios, antennas, filters, and other RF components, allowing you to integrate LMR-400 into new or existing systems without adapters in many cases. With its combination of solid construction, reliable mechanical coupling, and compatibility with low-loss LMR-400 cable, this SMA Female Straight Connector is a smart choice for anyone looking to build or upgrade high-quality RF cable assemblies with confidence.
