Coaxial cable Rangeful RP-SMA to N connector HF240 3 m pure copper

Rangeful HF240 3 m coaxial cable with RP-SMA male to N male connectors is designed for RF signal transmission and antenna connections where low loss and reliable connectivity are required. Constructed with pure copper conductors and dielectric optimized for HF240 performance, this cable supports applications in Wi‑Fi, cellular networks and general radio frequency equipment. The 3‑meter length provides flexibility for indoor and sheltered outdoor installations while maintaining consistent signal transfer.

Advantages

The cable combines pure copper conductors with HF240 dielectric characteristics to reduce insertion loss and preserve signal integrity across common RF bands. RP-SMA male and N male connectors offer secure, threaded mating suitable for many consumer and professional antennas and devices. The 3 m length balances reach and manageable attenuation for short to medium runs. Its construction supports straightforward installation and stable mechanical connection in fixed setups.

Suitable for

• Connecting Wi‑Fi routers and external antennas
• Cellular signal boosters and external modem antennas
• General RF test setups and laboratory equipment
• Short to medium length antenna installations in sheltered outdoor or indoor environments

Key specifications

• Cable type: HF240 coaxial
• Conductor material: pure copper
• Connector A: RP‑SMA male (reverse polarity SMA male)
• Connector B: N male (threaded N male)
• Length: 3 meters
• Typical use: RF signal transmission and antenna connections
• Environment: indoor and sheltered outdoor use

How to use

Before installation, verify that the RP‑SMA and N connector types are compatible with your devices and antennas. Align connectors carefully and thread the N connector until hand‑tight to avoid cross‑threading; secure the RP‑SMA connection according to the device’s mating instruction. Route the cable to avoid sharp bends and pinch points; maintain a bend radius consistent with HF240 cable recommendations to preserve performance. For permanent outdoor exposure, use additional weatherproofing at connector interfaces and ensure mounting points do not stress the cable.

Usage recommendations

For best RF performance, minimize cable length where possible and avoid repeated flexing. Use appropriate torque and sealing methods on N connectors in environments with moisture. Confirm device antenna polarization and connector gender before purchase to ensure compatibility.
