Long, flexible WiFi antenna jumper cable that connects devices with RP‑SMA and SMA connectors. Ideal for relocating antennas, extending reach, or adapting between connector genders without moving your router or modem. Why you need it Extend antenna placement up to 400 cm (4.0 m) to improve coverage and reduce interference from obstructions. Adapt between RP‑SMA female jack and SMA male plug so you can connect devices and antennas with mismatched connectors. Keep equipment in its original location while positioning the antenna for signal — no drilling or permanent changes required. Key features Connectors: RP‑SMA female jack to SMA male plug — matches common WiFi antenna and router connector types. Length: 400 CM (4.0 meters) for flexible placement options. Cable type: RG58 coaxial cable construction for standard RF signal transmission. Easy installation: screw‑on style SMA/RP‑SMA connection for straightforward, tool‑ attachment. Purpose: Designed as a jumper/extender for WiFi antennas and other compatible RF devices. Compatibility Works with devices using RP‑SMA and SMA connector interfaces, such as many routers, access points, USB WiFi adapters, and external antennas that require this gender/connector combination. Use to connect an external antenna to a base unit, or to adapt antenna connectors where one end uses RP‑SMA female and the other uses SMA male. Practical use cases Improve home WiFi coverage by moving the antenna to a higher or more central location within a room without moving the router. Connect an external antenna on a vehicle or mast to an indoor modem or access point while keeping the main unit sheltered and stationary. Test or prototype wireless setups by temporarily linking antennas and devices with mismatched connectors during installation or troubleshooting. What this cable solves Eliminates the need to relocate bulky equipment just to get the antenna into a better position. Removes incompatibility barriers between RP‑SMA and SMA connector devices so you can reuse antennas or install replacements quickly. Provides a clean, non‑permanent way to experiment with antenna placement for signal performance. Notes Cable specification: RG58 coaxial jumper, 400 CM length. Connector genders and types: RP‑SMA female jack on one end, SMA male plug on the other end. this RP‑SMA female jack to SMA male plug 400 CM RG58 jumper cable when you need a reliable, long‑reach connection between WiFi antennas and equipment with differing SMA connector types.
