Looking for a reliable way to relocate your antenna to improve signal reception with your router or device featuring RP-SMA (Reverse Polarity) connectors?
This cable is the perfect solution for moving the external antenna of your WiFi router, 3G/4G modem, video transmitter, or telemetry system to a more advantageous position.
This adapter cable is manufactured to the RP-SMA (Reverse Polarity) standard. Remember the simple rule for reverse polarity connectors: The RP-SMA Male features external threads and a hole (female pin) in the center, while the RP-SMA Female features internal threads and a male pin in the center. This cable is ideal for equipment from popular brands (including many router models, Ubiquiti and MikroTik access points, and radio modules labeled RP-SMA).
Why choose this extension cable?
Low Signal Loss: Constructed from high-quality RG174 coaxial cable, perfect for short to medium distances (up to 5-10 meters). You maintain signal power when moving your antenna away from a metal cabinet, placing it above obstructions, or even outdoors (provided additional waterproofing is used).
Versatile Applications:
Boost WiFi router signal (2.4 GHz / 5 GHz).
Connect an external antenna to 3G/4G modems and cellular signal boosters.
Extend antennas for FPV equipment (drone video transmitters).
Use with LoRa, Zigbee radio modules, and telemetry systems.
Reliable Connection: Brass SMA connectors with a gold-plated center pin ensure a secure connection and excellent corrosion resistance. The threaded coupling guarantees the cable won't accidentally detach from your router, unlike fragile U.FL (IPEX) type connectors.

Package Options:
Use the dropdown menu on the right to select the optimal model for your needs:
Adapter / Right Angle Connector RP SMA JW - K, 10 cm – Ideal for connections in tight spaces or direct attachment to a device enclosure without creating a "loop".
Extension Cable RP SMA-K, 5 m – The optimal choice for moving your antenna into a zone with reliable indoor reception.
Extension Cable RP SMA-K, 10 m – For maximum distance between the antenna and the source of interference or the router itself.
Important! Before ordering, please verify that your device (router, antenna, module) is equipped with reverse polarity RP-SMA connectors. If your equipment uses standard (non-reverse) SMA connectors, please check other items in our store.
