Coaxial RF cable Rangeful RP‑SMA Male to RP‑SMA Female HF240 50 Ω, 3 m

Rangeful HF240 coaxial RF cable with RP‑SMA male to RP‑SMA female connectors, 50 Ω impedance and 3 m length is designed for reliable RF signal transmission between compatible devices. The cable uses HF240 dielectric to maintain consistent characteristic impedance and limit signal loss over its 3 meter span, enabling stable connections for installations, test setups and radio-frequency communications where RP‑SMA terminations are required.

Advantages

This RF cable provides a standardized 50 Ω impedance for minimal reflection and consistent performance across common Wi‑Fi, cellular and RF test frequencies. The reverse‑polarity SMA connectors (RP‑SMA male to RP‑SMA female) ensure correct mating with devices that use RP‑SMA terminations, reducing the risk of connector incompatibility. The 3 m length offers flexibility for equipment placement without excessive loss, and the HF240 dielectric contributes to controlled velocity of propagation and predictable attenuation characteristics.

Suitable for

• Connecting antennas to routers, access points or radio modules with RP‑SMA interfaces
• Laboratory and field test setups requiring a 50 Ω coaxial link
• Amateur radio and hobbyist RF projects using RP‑SMA connectors
• Temporary installations where a moderate cable length is needed between components

Key specifications

• Connector type: RP‑SMA male to RP‑SMA female
• Impedance: 50 Ω characteristic impedance
• Cable dielectric: HF240
• Length: 3 meters
• Application: RF signal transmission for antennas, routers, radio modules and test equipment

How to use

Inspect both connectors and device ports for damage or debris before connecting. Align the RP‑SMA male and RP‑SMA female connectors and screw them together by hand until snug; avoid over‑tightening with tools to prevent damage to the connector threads and center conductors. Route the cable to avoid sharp bends, kinks and sources of mechanical stress. For test measurements, record connection points and maintain consistent connector torques to ensure repeatable results.

Usage recommendations

Use this 3 m HF240 RP‑SMA cable in environments within standard indoor operating conditions and keep the connector interfaces dry and clean. For outdoor or permanent installations, consider additional environmental protection such as weatherproof boots or conduit. If you require higher frequencies or lower loss over longer runs, evaluate alternative cable types or shorter connection paths.
