Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ω, 1 m

Rangeful HF240 is a 1 m coaxial cable with a BNC male connector at one end and an SMA male connector at the other, engineered for 50 Ω systems. The cable provides a compact, low-loss RF link for connecting test instruments, radio transceivers, antennas and communication modules that use BNC and SMA interfaces. Its single-metre length is convenient for bench setups and short patch connections where controlled impedance and connector compatibility matter.

Advantages

The cable offers consistent 50 Ω impedance throughout its length to minimise signal reflection and insertion loss in RF paths. Durable BNC and SMA male connectors ensure secure mechanical mating and repeatable electrical contact. The construction balances flexibility for routing on a bench with sufficient shielding to reduce external interference. The 1 m length simplifies placement between nearby devices without excess slack.

Suitable for

• Connecting laboratory test equipment (spectrum analyzers, signal generators) to devices with differing RF connectors
• Short links between radio transceivers and external antennas
• Prototyping and bench work where SMA and BNC interfaces need to be joined
• Communication devices and modules requiring a 50 Ω interconnect

Key specifications

• Impedance: 50 Ω
• Length: 1 m
• Connector types: BNC male to SMA male
• Typical use: RF interconnection for test, radio and communication equipment
• Cable category: coaxial, shielded for RF applications

How to use

Ensure both devices are powered down or set to safe RF levels before connecting. Align the BNC male connector with the BNC female socket and push-and-twist until the bayonet locks; align the SMA male with the SMA female and tighten by hand or with a small torque wrench to the recommended torque for SMA connectors to avoid overtightening. Route the cable to avoid sharp bends and crushing; maintain the cable radius recommended for coaxial lines to preserve characteristic impedance. After installation, verify continuity and check for expected signal levels or return loss with appropriate test equipment.

Usage recommendations

Use the cable for short, low-loss connections in 50 Ω RF systems. Avoid repeated excessive flexing at the connector junctions and do not exceed the connector torque limits. For long-term outdoor use or in corrosive environments, consider cables and connectors specified for environmental protection.
