Coaxial cable Rangeful RP-SMA Male to RP-SMA Female HF400 25 m, full copper, 50 Ω

Rangeful HF400 RP-SMA Male to RP-SMA Female coaxial cable, 25 m, is a flexible RF interconnect designed for 50 Ω systems. Constructed with full copper conductors and HF400 dielectric assembly, the cable supports stable signal transmission over long runs and is fitted with RP-SMA male on one end and RP-SMA female on the other for compatibility with devices that use reversed-polarity SMA connectors. Its 25 m length allows antennas, routers or test instruments to be positioned at a distance while preserving electrical characteristics required for RF applications.

Advantages

The full copper center conductor and copper shielding provide low resistance and reliable conductivity, helping to reduce insertion loss and preserve signal quality across the 25 m length. The HF400 cable construction offers consistent 50 Ω impedance and mechanical flexibility for routing through equipment racks or along walls. RP-SMA male to RP-SMA female terminations make the cable immediately compatible with a wide range of routers, modems, antennas and RF test adapters that use reversed-polarity SMA interfaces.

Suitable for

• Connecting external antennas to routers and wireless access points
• Linking RF test equipment, spectrum analyzers or signal generators with RP-SMA ports
• Extending antenna placement for better coverage in indoor or outdoor setups
• Temporary or permanent installations where a 25 m coaxial run is required

Key specifications

• Cable type: HF400 coaxial
• Length: 25 m
• Impedance: 50 Ω
• Conductor material: full copper center conductor
• Shielding: copper braid/foil (copper-based shielding)
• Connector 1: RP-SMA male
• Connector 2: RP-SMA female
• Typical use: RF/antenna interconnects, wireless equipment, test setups

How to use

Connect the RP-SMA male end to the RP-SMA female port on your antenna or device and attach the RP-SMA female end to the RP-SMA male port on the router, modem or test instrument as required. Ensure connectors are hand-tightened to avoid over-torquing and potential connector damage. Route the cable to minimize sharp bends and avoid kinks; maintain bend radii consistent with HF400 cable flexibility. For outdoor routing, protect connectors and exposed cable sections from moisture and UV with appropriate weatherproofing.

Usage recommendations

For best RF performance, keep the cable length as short as practical for your installation, avoid coiling the cable tightly, and secure it with non-constricting ties. When used with high-power transmitters, verify that all connectors are properly seated and periodically inspect the cable for wear or corrosion to maintain consistent 50 Ω performance.
