Coaxial cable Rangeful RP‑SMA Male to RP‑SMA Female HF240 3 m pure copper

Rangeful HF240 coaxial cable with RP‑SMA male to RP‑SMA female connectors, 3 m length, uses a pure copper center conductor and is designed for RF and antenna connections that require RP‑SMA termination. The cable supports short to medium runs with low insertion loss and stable impedance, making it appropriate for extending antennas or connecting wireless routers, modems and other RF devices that use RP‑SMA interfaces.

Advantages

The pure copper conductor ensures good electrical conductivity and consistent signal transfer. RP‑SMA male to RP‑SMA female termination provides compatibility with devices using reverse‑polarity SMA connectors, enabling straightforward plug‑and‑play extension of antenna leads. At 3 meters, the cable balances reach and signal integrity for many indoor and sheltered outdoor applications. The HF240 dielectric and shielding construction reduce interference and maintain stable impedance across common Wi‑Fi and cellular frequencies.

Suitable for

• Extending external antennas for routers and access points
• Connecting modems and cellular gateways to remote antennas
• Linking wireless communication modules and RF test equipment
• Replacing or routing antenna leads in IoT and smart home installations

Key specifications

• Cable type: HF240 coaxial
• Connector configuration: RP‑SMA male to RP‑SMA female
• Conductor material: pure copper center conductor
• Length: 3 meters
• Impedance: 50 ohm (typical for RP‑SMA applications)
• Intended use: RF/antenna connections for Wi‑Fi, cellular and other wireless bands

How to use

Connect the RP‑SMA male end to the RP‑SMA female port on the device that requires the antenna or extension connection, and attach the RP‑SMA female end to the antenna or the accessory with an RP‑SMA male port. Tighten connectors by hand until snug; avoid overtightening with tools to prevent damage to connector threads. Route the cable to minimize sharp bends and avoid running it parallel and close to power cabling or strong EMI sources. For outdoor routing, use appropriate cable clips and grommets where the cable passes through walls or enclosures to protect the jacket and maintain signal integrity.

Usage recommendations

For best performance, keep the cable length as short as practical for your setup, and avoid kinking the cable. Verify device compatibility with RP‑SMA reverse‑polarity connectors before connection. If used in exposed outdoor environments, consider additional protection such as weatherproof boots or sealing at connector interfaces to prolong service life.
