RP-SMA Female RF Connector – Reliable Crimp Termination for Wi-Fi, GPS and Telecom Cables

High-Quality 50-Ohm Reverse Polarity Connector for RG58, LMR195, RG142 and RG400 Cables

This RP-SMA (Reverse Polarity SMA) female RF connector is designed for crimp termination on various thin coaxial cables, including RG58 U, LMR195, RG142 and RG400. It provides a reliable RF interface for connecting cables to antennas, wireless modules, Wi-Fi devices, radio equipment and other components using RP-SMA connectors.

Key Features:
✔ Connector Type: Reverse-polarity RP-SMA female — featuring an RP-SMA interface with threads and a central pin arrangement as defined in RF connector standards;
✔ Mounting Method: Crimp termination — the connector is attached by crimping to the coax cable’s outer braid for a secure, low-loss connection;
✔ Compatible Cables: Designed for RG58 U, LMR195, RG142, RG400 coaxial cables — common 50 Ω RF cables;
✔ Impedance: 50 Ω — standard for RF systems, ensuring good signal transfer;
✔ Applications: Ideal for connecting antennas, radios, wireless modules, GPS systems, IoT devices and other RF equipment.

Installation:
This adapter is typically installed using crimp tools that secure its ferrule to the coaxial cable’s shield. The center conductor is often soldered to the connector’s pin to improve electrical contact and robustness. This installation method yields strong, reliable RF performance with low signal loss.

Typical Uses:
✔ Connecting antennas to Wi-Fi routers, IoT hubs and wireless modules;
✔ RF communication systems, amateur radio and professional RF equipment;
✔ Custom RF cabling and antenna assemblies;
✔ GPS and satellite antenna connections where RP-SMA is required;
✔ Cable repairs and RF installations in labs or field environments.

Benefits:

• Works with multiple types of RF coax cables for versatile integration;

• Reverse polarity (RP-SMA) ensures correct mating with RP-SMA antennas and devices;

• Crimp termination provides secure, low-loss RF connections;

• Compact and robust design for professional installations.
