Coaxial cable Rangeful HF240 SMA male to N male 50 Ω, 7 m

Rangeful HF240 coaxial cable with an SMA male connector on one end and an N male connector on the other provides a 50 Ω transmission line in a 7 m length. The cable is intended for RF signal transmission and antenna connections where consistent 50 ohm matching is needed. Its flexible construction and threaded connectors enable secure physical and electrical connections between test equipment, radios, and antennas while allowing routing over moderate distances.

Advantages

The cable offers reliable 50 Ω impedance throughout its length, reducing reflections and preserving signal integrity for RF applications. Threaded SMA male and N male connectors provide strong mechanical retention and good electrical contact suitable for repeated connections. The 7 m length allows flexibility in equipment placement and antenna positioning without intermediate adapters, and the cable's flexibility supports tidy routing in lab or field setups.

Suitable for

• Connecting antennas to transceivers and receivers
• RF test benches and measurement equipment
• Temporary or semi-permanent installations in communications systems
• Prototyping and development of RF devices
• Field testing and site surveys requiring flexible cable runs

Key specifications

• Characteristic impedance: 50 Ω
• Connector type: SMA male to N male
• Cable length: 7 m
• Cable type: flexible RF coaxial
• Typical use: RF signal transmission and antenna connections

How to use

Verify that both connected devices accept 50 Ω cabling and compatible connector genders. Align the SMA male and N male connectors to the device ports, screw the connectors gently by hand until finger-tight, then secure with a torque wrench to the manufacturer's recommended torque if precision mating is required. Avoid sharp bends near the connectors and route the cable to prevent kinks; maintain a minimum bend radius consistent with flexible coaxial cable handling. When disconnecting, unscrew the connectors fully before pulling to avoid damaging the mating surfaces.

Usage recommendations

For best RF performance, minimize unnecessary cable length and avoid prolonged exposure to water or corrosive environments. Inspect connector threads and center contacts before use, and store the cable coiled without tight loops. Use appropriate torque values when tightening connectors to ensure repeatable impedance and mechanical stability.
