Generic 15cm RP-SMA Female to Stripping Head Cable RG1.13

RP-SMA stands for Reverse Polarity SubMiniature version A. It features reversed gender roles for the center pin and socket compared to standard SMA connectors. Specifically, the RP-SMA male has a hollow center sleeve, while the female has a solid center pin. This design is often used on consumer Wi-Fi equipment to prevent users from attaching high-gain external antennas, ensuring compliance with regulatory limits.

The stripping head exposes the coaxial cable's inner conductor and shield. To connect it, strip a small section of your antenna wire or prepare a PCB pad. Solder the central core wire to your antenna's active element and the braided shield to the ground plane. Ensure a clean, short solder joint and use heat-shrink tubing to insulate the connection, preventing short circuits and maintaining the cable's 50-ohm impedance for optimal RF performance.

RG1.13 coaxial cable is suitable for frequencies commonly used in Wi-Fi (2.4GHz & 5GHz), cellular (4G/LTE), and GPS bands. Its compact diameter and flexibility make it ideal for short internal runs within devices like routers, IoT gateways, or drones. For longer runs or higher frequencies, consider lower-loss cables like RG316. Always ensure impedance matching (50 ohms) between your source, cable, and antenna to minimize signal reflection.
