Coaxial cable Rangeful HF240 SMA male to RP‑TNC male, 50 cm, 50 Ω

Rangeful HF240 coaxial cable with an SMA male connector on one end and an RP‑TNC male connector on the other provides a 50 cm interconnect solution for RF applications requiring 50 Ω impedance. The cable is intended for signal transmission between devices with SMA and reverse‑polarity TNC ports and is suitable for installations where a compact, flexible jumper is needed to connect antennas, routers, modems and laboratory instruments. The construction balances flexibility and shielding to preserve signal integrity across common cellular, Wi‑Fi and other RF bands supported by connected equipment.

Advantages

The HF240 cable offers consistent 50 Ω characteristic impedance and secure SMA‑to‑RP‑TNC mating to minimise mismatch losses. Its flexible jacket and compact 50 cm length make routing in cramped spaces straightforward while maintaining mechanical stability of the connectors. The cable design reduces handling strain on device ports and supports repeated connector cycles typical in testing and field installations.

Suitable for

• Connecting antennas to routers, modems and wireless access points with SMA or RP‑TNC ports
• Linking RF modules and test equipment in bench and field testing
• Temporary or permanent jumper runs in networking and telecommunications setups

Key specifications

• Impedance: 50 Ω
• Length: 50 cm
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse‑polarity TNC)
• Cable type: coaxial, flexible jacket
• Typical use: RF signal transmission for antennas, routers, modems, test equipment

How to use

Verify that both connected devices support 50 Ω systems and that the SMA and RP‑TNC connector genders match the equipment ports. Align the connectors carefully and hand‑tighten the SMA and RP‑TNC interfaces to ensure a secure electrical contact; avoid over‑tightening with tools to prevent damage. Route the cable to avoid sharp bends with radius smaller than the cable’s bending specification and keep it clear of high‑power conductors and sources of electromagnetic interference where possible.

Usage recommendations

For reliable performance, use the cable within the operating frequency range supported by your equipment and inspect connectors for damage before installation. When used in test setups, label each jumper for easy identification and replace the cable if repeaters or excessive connector wear is observed.
