Description

This RP-SMA female to stripping head cable is a fundamental RF interconnect for developers and integrators working with wireless systems. The 25cm RG1.13 coaxial cable maintains a consistent 50-ohm characteristic impedance, minimizing signal reflection and insertion loss for frequencies commonly used in Wi-Fi, Bluetooth, and cellular applications. The RP-SMA female connector is engineered with a gold-plated brass body and a beryllium copper center contact to ensure durable, low-resistance mating with compatible male RP-SMA jacks found on many commercial wireless devices.

The opposite end is terminated as a stripping head, exposing the central conductor and shield of the coaxial cable. This design provides maximum flexibility, allowing the user to solder directly to a PCB antenna pad, crimp on a different connector type, or attach to a custom antenna element. The cable’s short length and RG1.13 diameter make it ideal for internal device wiring, lab bench testing, or field repairs where a pre-terminated pigtail is not suitable. Its construction supports reliable performance for prototyping IoT gateways, extending router antennas, or connecting RF test equipment.

Key Features

  • Reverse Polarity SMA (RP-SMA) female connector with external threads and a center pin.
  • Gold-plated brass connector body and beryllium copper center contact for optimal conductivity and corrosion resistance.
  • Stripping head termination for custom soldering or connection to antenna elements, PCB pads, or other interfaces.
  • RG1.13 coaxial cable with 50-ohm impedance, suitable for Wi-Fi, Bluetooth, and other 2.4GHz/5GHz ISM band applications.
  • Includes a 5/16" hex nut (bulkhead nut) for secure panel or enclosure mounting.
  • PTFE (Teflon) insulator material provides stable dielectric properties and heat resistance.
  • 25cm cable length offers flexibility for short-run internal wiring within devices or enclosures.
  • Designed to prevent unauthorized antenna connections on consumer devices while enabling developer access.

Applications

  • Extending or replacing internal antennas in Wi-Fi routers, access points, and cellular gateways.
  • Prototyping custom antenna connections for IoT development boards (ESP32, Raspberry Pi, LTE modules).
  • Creating test leads for RF signal analysis and wireless device debugging.
  • Field repairs and modifications for wireless networking equipment and telemetry devices.
  • Connecting RF modules to external antenna ports in enclosed industrial or automotive applications.

Frequently Asked Questions

What is the difference between SMA and RP-SMA connectors?

RP-SMA (Reverse Polarity SMA) reverses the gender of the inner conductor and outer shell compared to standard SMA. In an RP-SMA female connector, the center contact is a pin, while the standard SMA female has a socket. This design is often used by consumer device manufacturers to prevent connection of non-standard external antennas. Always verify your device's port type before purchasing a cable.

How do I terminate the stripping head end of this cable?

The stripping head exposes the central conductor and braided shield. To terminate, strip a small section of the outer jacket, separate the shield braid, and tin the center conductor with solder. You can then solder it directly to a PCB antenna pad, a connector like an IPEX/U.FL plug, or a custom wire antenna. Ensure a clean, short connection and use heat shrink to insulate the joint for mechanical stability and signal integrity.

Is this RG1.13 cable suitable for 5.8GHz drone FPV systems?

While RG1.13 is a lightweight coaxial cable, its attenuation increases significantly at higher frequencies like 5.8GHz. For short runs (under 25cm) in low-interference environments, it may function, but for optimal FPV video signal range and clarity, a lower-loss cable like RG316 or LMR-100 is recommended. Always use the shortest cable possible and ensure proper impedance matching for critical RF links.
