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

Rangeful HF240 coaxial cable with SMA male to SMA female connectors, 50 Ω impedance and 3 m length provides a flexible RF interconnect for devices with SMA interfaces. The cable is intended for use in antenna connections, RF testing setups, amateur radio and Wi‑Fi systems where maintaining a matched 50 Ω signal path is important. Its 3 metre length allows comfortable routing between rack-mounted equipment, test instruments and antennas while the SMA male to SMA female terminations enable straightforward connection without adapters.

Advantages

The construction offers consistent 50 Ω characteristic impedance to minimise reflections and preserve signal integrity across a range of RF applications. SMA male to SMA female connectors give a secure threaded connection that resists accidental disconnection. The cable's flexibility and length simplify installation in confined spaces and around equipment racks. Designed for general RF use, it is compatible with common test instruments, antennas and transceivers that accept SMA terminations.

Suitable for

• Connecting antennas to routers, access points or radios with SMA ports
• RF test setups and laboratory measurements
• Amateur radio installations and temporary field setups
• Wi‑Fi equipment extension or replacement of short patch cables

Key specifications

• Impedance: 50 Ω
• Connector type: SMA male to SMA female
• Length: 3 m
• Cable type: flexible coaxial RF cable
• Typical use: RF signal transmission between SMA‑terminated devices

How to use

Connect the SMA male end to the female SMA jack on the transmitting or source device and attach the SMA female end to the male SMA connector on the receiving device or antenna. Ensure threaded SMA connections are hand‑tightened to establish firm mechanical contact without over‑torquing. Route the cable to avoid sharp bends and kinks; maintain gentle curves consistent with the cable's minimum bend radius to avoid degrading performance. For test measurements, allow stable seating of connectors before recording data.

Usage recommendations

Use the cable only for 50 Ω systems to maintain impedance matching; do not subject connectors to excessive mechanical stress or repeated rough handling. For outdoor or permanently exposed installations, consider additional environmental protection or a cable specifically rated for outdoor use. Periodically inspect connectors for dirt or corrosion and clean with appropriate, non‑abrasive methods if necessary.
