Coaxial cable Rangeful SMA male to N female RG58/U 50 Ω, 7 m

Rangeful 7-meter RG58/U coaxial cable with SMA male to N female connectors provides a flexible 50 Ω interconnect for RF signal transmission between devices with SMA and N interfaces. The cable is intended for temporary or semi-permanent connections where a mid-length lead is required, allowing measurements, antenna feeding, and connections between test instruments and communication equipment. The RG58/U construction balances flexibility and consistent characteristic impedance for use in laboratory, field, and installation scenarios.

Advantages

The cable combines a commonly used RG58/U dielectric and shielding structure with precision SMA male and N female terminations to ensure reliable contact and stable 50-ohm transmission. Its 7 m length gives enough reach for many bench and field setups while remaining flexible for routing and handling. The N female connector offers robust mating with N male devices, and the SMA male fits compact, threaded SMA ports, making the assembly suitable for mixed-interface systems without adapters.

Suitable for

• Connecting antennas to transceivers or receivers with differing SMA/N interfaces
• Laboratory test setups and temporary measurement connections
• Radio and communication system installations where a mid-length 50 Ω cable is needed
• Interfacing RF signal generators, spectrum analyzers, and other test equipment

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 ohm nominal
• Length: 7 meters
• Connector A: SMA male (threaded)
• Connector B: N female (threaded, bulkhead-compatible)
• Typical usage: RF signal transmission, measurement, antenna feed

How to use

Inspect both connector interfaces and the cable for visible damage before use. Securely hand-tighten the SMA male to the mating SMA connector, taking care not to cross-thread the fine SMA threads. Align the N female with the corresponding N male connector and tighten using an appropriate torque wrench or hand-tighten to manufacturer-recommended torque for a reliable RF connection. Route the cable to avoid sharp bends and excessive tension; keep bend radius larger than the cable's minimum specification to preserve impedance and reduce loss. When disconnecting, loosen connectors carefully to avoid damaging threads or the inner conductor.

Usage recommendations

For consistent measurement results and prolonged cable life, avoid repeated sharp bends and minimize exposure to moisture and corrosive environments; use proper connector torque and, if required, protective covers or weatherproofing for outdoor installations.
